EXPLANATORY NOTE
(This explanatory note is not part of the Notice.)
Exposure to nitrogen dioxide (NO2) in the air is associated with both direct and indirect effects on human health and the environment. Direct inhalation of NO2 can adversely affect respiratory function and has also been linked to effects on the cardiovascular system, as well as on fetal growth and birth weight. Direction inhalation of NO2 has also been linked to premature death. Studies indicate that NO2 can adversely affect the health of Canadians even at low concentrations. Direct exposure of plants to NO2 can cause a decrease in the quality, growth and yield of vegetation (including crops), with related financial losses. NO2 contributes to the formation of acid rain, which can be deposited onto soils and surface waters and can cause deforestation, acidify rivers and lakes to the detriment of aquatic life, and corrode buildings, bridges and other infrastructure. Continued deposition of acidic compounds (especially at levels beyond what the ecosystems can tolerate) can lead to significant stress to the environment. Additionally, NO2 also contributes to eutrophication of ecosystems, which is associated with a number of adverse effects such as excessive growth of algae, which can be lethal for fish and reduce the biodiversity of vegetation species. The latest scientific information supports the need for both short-term (one hour) and long-term (annual) ambient air quality standards for NO2 to address these effects on human health and the environment.
NO2 is also a precursor pollutant that contributes to the formation of fine particulate matter (PM2.5) and ground-level ozone (ozone) for which Canadian Ambient Air Quality Standards (CAAQS) were published in the Canada Gazette, Part I, on May 25, 2013. Exposure to these two pollutants increases the risk of adverse human health effects contributing to respiratory and cardiovascular disease and premature death. Ozone can also adversely impact the growth and yield of vegetation (including crops) and PM2.5 can impair visibility and cause haze in some parts of Canada, all of which can result in substantial economic losses. Ozone is also a potent greenhouse gas and a short-lived climate pollutant that contributes to near-term climate change.
The CAAQS were developed considering health and environmental impacts and are intended to drive continuous improvement of air quality in Canada. The CAAQS were developed collaboratively by Health Canada, Environment and Climate Change Canada, provinces, territories, Indigenous peoples' representatives, and stakeholders from industry, health, and environmental organizations through a consensus-based process under the Canadian Council of Ministers of the Environment (CCME).
The CAAQS are a key element of the Air Quality Management System (AQMS), a collaborative approach implemented by federal, provincial and territorial governments for improving air quality in Canada and for protecting the health of Canadians and the environment. As part of the continuing implementation of the AQMS, CCME endorsed the CAAQS for NO2 in November 2017.
The AQMS is comprehensive, considering all significant sources of air pollutant emissions, and providing a consistent, yet flexible, framework to implement air quality management actions. These actions are guided by the Air Zone Management Framework (see footnote 2) of CCME, which includes four air quality management levels that encourage progressively more rigorous actions by jurisdictions as air quality approaches or exceeds the CAAQS, thereby ensuring that the CAAQS are not pollute-up-to levels.
The management levels for the CAAQS for NO2 are summarized in the table below.
| Air quality management levels (see footnote 3) and goals | Range of Ambient Air Pollutant Concentrations | |||
|---|---|---|---|---|
| NO2 1-hour CAAQS (see note a) (ppb) |
NO2 Annual CAAQS (see note b) (ppb) |
|||
| 2020 | 2025 | 2020 | 2025 | |
| RED Reduce ambient air pollutant concentrations below the CAAQS |
>60 | >42 | >17.0 | >12.0 |
| ORANGE Prevent CAAQS exceedance |
>31 and ≤60 | >31 and ≤42 | >7.0 and ≤17.0 | >7.0 and ≤12.0 |
| YELLOW Prevent air quality deterioration |
>20 and ≤31 | >2.0 and ≤7.0 | ||
| GREEN Keep clean areas clean |
≤20 | ≤2.0 | ||
Note a: The concentrations have the same statistical form as their corresponding CAAQS (see the Annex above).
Note b: The concentrations have the same statistical form as their corresponding CAAQS (see the Annex above).
To assist in the management of the air quality, provinces and territories have delineated their jurisdictions into local areas called air zones that have different air quality characteristics that are influenced by the number and type of air pollutant sources, meteorology and topography. Provinces and territories lead air quality management actions in the air zones, guided by a number of guidance documents developed by CCME in consultation with stakeholders.
Under the AQMS, federal, provincial and territorial governments have agreed to report regularly on air quality and on the management actions undertaken to improve air quality.

ANNEX
Summary of the draft screening assessment of the Carboxylic Acid Anhydrides Group
Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment of three of the eight substances referred to collectively under the Chemicals Management Plan as the Carboxylic Acid Anhydrides Group. These three substances were identified as priorities for assessment, as they met categorization criteria under subsection 73(1) of CEPA. The other five substances were determined to be of low concern through other approaches, and decisions for these substances are provided in separate reports. (see footnote 5) Accordingly, this screening assessment addresses the three substances listed in the table below.
| CAS RN (see footnote 6) | Domestic Substances List name | Common name |
|---|---|---|
| 85-44-9 | 1,3-Isobenzofurandione | Phthalic anhydride |
| 108-31-6 | 2,5-Furandione | Maleic anhydride |
| 552-30-7 | 5-Isobenzofurancarboxylicacid, 1,3-dihydro-1,3-dioxo | Trimellitic anhydride |
In 2011, imported quantities of phthalic anhydride and trimellitic anhydride were <12 550 000 kg and 1 000 000–10 000 000 kg, respectively, based on surveys issued pursuant to section 71 of CEPA. The two substances were not reported as being manufactured in Canada above the reporting threshold of 100 kg. Maleic anhydride was not included in surveys pursuant to section 71 of CEPA; however, Canadian average annual import volumes of maleic anhydride from 2013 to 2016 were approximately 9 000 000 kg.
All of the substances in the Carboxylic Acid Anhydrides Group are primarily used as intermediates in the production of other chemicals. The substances in this group do not naturally occur in the environment. Phthalic anhydride may be formed through the photochemical breakdown of other organic substances in air.
Phthalic anhydride and maleic anhydride are present on the list of substances reported to the National Pollutant Release Inventory (NPRI). Phthalic anhydride and maleic anhydride have been reported to be released in quantities of 90 kg and 18 kg, respectively. A report from the National Research Council of Canada reported phthalic anhydride to be present in indoor air and dust in homes in Canada.
Phthalic anhydride is primarily used as a chemical intermediate for the synthesis of phthalate esters. It may also be used in the production of polyester resins, alkyd resins, and other chemical substances such as pigments and dyes. In Canada, phthalic anhydride is present in consumer spray paint products, floor polishes, and cosmetic products including nail polishes and eye adhesives. In Canada, it has also been identified for use in the manufacture of food packaging materials.
Based on available information, maleic anhydride is primarily used as a chemical intermediate in the synthesis of unsaturated polyester resins as well as other chemical substances. In Canada, maleic anhydride was identified as an ingredient in shampoos, bubble baths (oil and foam), body cleansers, bath salts, exfoliants, and temporary tattoos. Through safety data sheets, the substance was also identified in wood blending sticks designed to repair minor scratches on wood surfaces. Maleic anhydride has been identified in Canada for use in the manufacture of food packaging materials.
Trimellitic anhydride is used in commercial applications including paint and coating applications and plastic and rubber materials where it functions as an intermediate. The substance was identified for use as a component in resins used in the manufacture of returnable bottles used for milk, water, and juice. Trimellitic anhydride was reported to be used as an ingredient in one product available to consumers (i.e. nail polish) in Canada.
The ecological risks of the substances in the Carboxylic Acid Anhydrides Group were characterized using the Ecological Risk Classification (ERC) of organic substances. The ERC is a risk-based approach that employs multiple metrics for both hazard and exposure based on weighted consideration of multiple lines of evidence for determining risk classification. Hazard profiles are established based principally on metrics regarding mode of toxic action, chemical reactivity, food web–derived internal toxicity thresholds, bioavailability, and chemical and biological activity. Metrics considered in the exposure profiles include potential emission rate, overall persistence, and long-range transport potential. A risk matrix is used to assign a low, moderate or high level of potential concern for substances based on their hazard and exposure profiles. The ERC identified three of the substances in the Carboxylic Acid Anhydrides Group as having low potential to cause ecological harm.
Considering all available lines of evidence presented in this draft screening assessment, there is low risk of harm to organisms and the broader integrity of the environment from maleic anhydride, trimellitic anhydride and phthalic anhydride. It is proposed to conclude that maleic anhydride, trimellitic anhydride and phthalic anhydride do not meet the criteria under paragraph 64(a) or (b) of CEPA, as they are not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity or that constitute or may constitute a danger to the environment on which life depends.
Based on the available information, the critical effect for characterization of the risk to human health from exposure to phthalic anhydride is respiratory sensitization. A comparison of the estimated exposure levels of phthalic anhydride from its uses in products available to consumers including spray paints, floor polishes, and eye adhesives to critical effect levels resulted in margins of exposure that are considered adequate to account for uncertainties in the health and exposure databases. A comparison of estimated exposure to phthalic anhydride from its presence in indoor air to critical effect levels resulted in margins of exposure that are considered adequate to account for uncertainties in the health and exposure databases.
Based on the collective information, the critical effects for characterization of the risk to human health from exposure to maleic anhydride are effects on the kidneys and bladder. A comparison of estimated exposure levels from its uses in products available to consumers to critical effect levels resulted in margins of exposure that are considered adequate to account for uncertainties in the health and exposure databases.
The estimated exposure to trimellitic anhydride from environmental media or food packaging is expected to be negligible and exposure from the use of nail polish is not expected based on the substance function in the product. The overall exposure of the Canadian general population to trimellitic anhydride is negligible; therefore, the risk to human health is considered to be low.
Based on the information presented in this draft screening assessment, it is proposed to conclude that phthalic anhydride, maleic anhydride, and trimellitic anhydride do not meet the criteria under paragraph 64(c) of CEPA, as they are not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.
Proposed conclusion
It is proposed to conclude that phthalic anhydride, maleic anhydride and trimellitic anhydride do not meet any of the criteria set out in section 64 of CEPA.
The draft screening assessment for these substances is available on the Canada.ca (Chemical Substances) website.

ANNEX
Summary of the screening assessment of 14 substituted diphenylamines
Pursuant to section 68 or 74 of the Canadian Environmental Protection Act, 1999 (CEPA), the Minister of the Environment and the Minister of Health have conducted a screening assessment on 14 substituted diphenylamines (SDPAs). The SDPAs were identified as priorities for action as they met the categorization criteria under subsection 73(1) of CEPA or were considered a priority based on other human health concerns or on their potential use as alternatives for each other. One of these 14 SDPAs is benzenamine, N-phenyl-, reaction products with styrene and 2,4,4-trimethylpentene, known as BNST, which had previously been assessed during the Challenge initiative of the Chemicals Management Plan, and which is reassessed based on new information obtained after the original assessment.

SDPAs do not occur naturally in the environment. Based on the results of the mandatory and voluntary surveys for the years 2006, 2011, and 2012, and the DSL Inventory Update for 2008, they are used in high quantities in Canada. In 2011, between 1 000 000 and 10 000 000 kg of SDPAs were imported into Canada, either as individual substances or as part of specialty chemical additive packages, according to the results of the CEPA section 71 survey. In the same year, over 10 000 000 kg of SDPAs were also manufactured in Canada, the majority (over 90%) of which was exported. CAS RN 68921-45-9 (BNST) was not surveyed in 2011. For BNST, between 100 000 and 1 000 000 kg of this SDPA was imported into Canada in 2006, and between 1 000 000 and 10 000 000 kg was manufactured in 2006 according to the results of the CEPA section 71 survey. The major uses of SDPAs in Canada are as antioxidants in automotive and industrial lubricants. SDPAs are also used as antioxidants/antidegradants in the manufacturing of plastics or polyurethane foams and rubber products, and are imported in polymers or polyols.
Environmental exposure to SDPAs was examined in multiple scenarios representing industrial activities and overall uses of SDPAs in Canada. The key activities examined were the manufacturing of SDPAs and the blending of lubricants, which are the major anticipated sources of release to the environment. Additional activities were examined, including SDPA uses in the plastics and rubber sectors, automotive and powertrain assembly lines, disposal of lubricants, and biosolids amendment to agricultural land. These scenarios focused on the total representative SDPA structures, given that SDPAs are potential replacements for each other, and changes in product formulations could occur with the total SDPA usage remaining relatively constant.
SDPAs are characterized by low water solubilities, low vapour pressures and high to very high octanol–water partition coefficients. Among the SDPA structures, those with the log Kow of less than 9 (i.e. monooctyl DPA, dimethyl distyrenated DPA, monononyl DPA, monostyrenated DPA, distyrenated DPA, dibutyl DPA, monobutyl DPA, monobutyl monooctyl DPA and monooctyl monostyrenated DPA) are considered to be bioavailable, while those with the log Kow exceeding 9 (i.e. dioctyl DPA, dinonyl DPA, diethyl monononyl DPA and diethyl dinonyl DPA) are not easily absorbed from the exposure medium or diet and thus are considered to have very low bioavailability and have limited bioaccumulation potential. Due to their lack of bioavailability, dioctyl DPA, dinonyl DPA, diethyl monononyl DPA, and diethyl dinonyl DPA are considered to have a lower ecological hazard potential.
Due to their hydrophobic nature, SDPAs in the environment are primarily associated with sediments, suspended particulate matter and soil. They are considered to be persistent in the environment, but are not expected to undergo long-range transport in water or air. Therefore, long-term exposures are expected to be near discharge areas and closer to emission sources.
Analyses revealed that the potential for adverse effects from SDPAs in the environment, including benthic species, aquatic species (fish), piscivorous mammals, and soil-dwelling organisms, is low. The determination of SDPA toxicity in aquatic species is affected by their low water solubilities, where effects are observed at exposure concentrations that surpass substance solubility limits. Low toxicity to soil- and sediment-dwelling organisms was also observed in SDPA exposure studies using the earthworm and freshwater midge as test species, respectively. Toxicity to the representative piscivorous mammal species was evaluated using a read-across approach with rodent data, resulting in a toxicity reference value indicating potential for adverse effects (<10 mg/kg bw/day). To evaluate ecological effects of SDPAs, critical body burden (CBR) calculations were conducted for representative benthic species, aquatic species (fish), piscivorous mammals, and soil-dwelling organisms, and compared to the internal threshold levels of narcotic chemicals causing death. The CBR values were found to be below the threshold levels for both acute and chronic exposures, indicating minimal potential risk from exposure to SDPAs.
Considering all the lines of evidence presented in this screening assessment, there is currently a low risk of harm to organisms and the broader integrity of the environment from the 14 SDPAs considered in this assessment. It is concluded that the 14 SDPAs considered in this assessment do not meet the criteria under paragraph 64(a) or (b) of CEPA, as they are not entering the environment in a quantity or concentration or under conditions that have or may have an immediate or long-term harmful effect on the environment or its biological diversity or that constitute or may constitute a danger to the environment on which life depends.
The human health assessment considers all available lines of evidence on the 14 SDPA substances. For the human health assessment, exposure of the general population to SDPAs from environmental media is expected to be low, given the physical-chemical properties and use pattern of these substances. Exposure from food is not expected. Exposure of the general population from the use of products available to consumers results primarily from foam cushioning and automotive lubricants via oral and dermal routes, respectively.
Available empirical data for 8 of the 14 substances in this grouping indicates that these substances are not likely genotoxic. Based on the empirical data available for this substance grouping, health effects following short-term oral exposure in animal studies include the liver and hematological and/or clinical chemistry parameters. The kidney is a target organ at higher levels.
Comparisons of estimates of exposure of the general population to SDPAs from levels in environmental media and from use of products available to consumers with levels associated with adverse health effects are considered to be adequate to account for uncertainties in the health effects and exposure databases.
Based on the information presented in this screening assessment, it is concluded that the 14 SDPAs considered in this assessment do not meet the criteria under paragraph 64(c) of CEPA, as they are not entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health.
Overall conclusion
It is concluded that the 14 SDPAs considered in this assessment do not meet any of the criteria set out in section 64 of CEPA. This conclusion also applies to BNST, one of the 14 substances assessed; this substance had previously been found to meet the criteria set out in section 64 of CEPA in a 2009 screening assessment conducted during the Challenge initiative of the Chemicals Management Plan.
Considerations for follow-up
While exposure of the environment to SDPAs is not of concern at current levels, some of the representative chemical structures of SDPAs are bioavailable. Therefore, there may be a concern if environmental exposure were to increase. Follow-up activities for the substances identified by CAS RNs 4175-37-5, 10081-67-1, 27177-41-9, 36878-20-3, 68411-46-1, 68442-68-2, 68608-79-7, 68921-45-9, and 184378-08-3 will involve including the substance in future information-gathering initiatives, such as a mandatory survey under section 71 of CEPA.
The Government will use the data gathered through these follow-up activities to prioritize further information gathering or risk assessment of these substances, if required.
The screening assessment for these substances is available on the Canada.ca (Chemical Substances) website.

PROCEEDS OF CRIME (MONEY LAUNDERING) AND TERRORIST FINANCING ACT
Ministerial directive
Whereas section 11.42 of the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (the Act) gives the Minister of Finance the authority to issue a directive to any person or entity subject to the Act, in order to safeguard the integrity of Canada's financial system.
I issue the following directive:
Every person or entity referred to in section 5 of the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (the Act) shall treat all transactions originating from, or destined to, North Korea (Democratic People's Republic of Korea) as high risk for the purposes of subsection 9.6(3) of the Act.
Rationale for directive
The Minister of Finance has issued this directive in response to a call from the Financial Action Task Force, which called on its members to take measures in relation to North Korea on the grounds that the state's anti-money laundering or anti-terrorist financing measures are ineffective or insufficient.
Coming into force
This directive will come into force on the day of its publication in the Canada Gazette, Part I.
Termination date
This directive will apply until such time as it is amended or revoked by the Minister of Finance.

On February 11, 2015, the Hazardous Products Act (HPA) was amended and the Controlled Products Regulations (CPR) and the Ingredient Disclosure List were repealed and replaced with the new Hazardous Products Regulations (HPR). The revised legislation (HPA/HPR) is referred to as WHMIS 2015 and the former legislation (HPA/CPR) is referred to as WHMIS 1988. Transitional provisions allow compliance with either WHMIS 1988 or WHMIS 2015 for a specified period of time.
The claims listed below seek an exemption from the disclosure of supplier confidential business information in respect of a hazardous product; such disclosure would otherwise be required under the provisions of the relevant legislation.
