What are they?

• The five substances listed above are industrial chemicals.

How are they used?

• Based on the most recent data available, the five substances are not manufactured in or imported into Canada.

Why did the Government of Canada assess them?

• The five substances were identified as a potential concern to the environment based on available information regarding possible persistence, accumulation in organisms and potential to cause harm to organisms.
• The five substances were believed to be potentially in commerce in Canada prior to assessment.

How are they released into the environment?

• The Government of Canada has reviewed information that indicates that the five substances are not currently in commerce in Canada in significant quantities.
• As a result, it is unlikely that the substances are entering the environment as a result of commercial manufacture or use in this country.

What is the Government of Canada doing?

• The Government of Canada has conducted a science-based evaluation of the five substances called a screening assessment.
• The Government of Canada has concluded that the five substances are not entering the environment in a quantity or under conditions that constitute a danger to the environment.
• The Government of Canada will consider implementing a Significant New Activity or SNAc provision for the five substances. This would require that any proposed uses of the substances be subject to further assessment before this new activity would be allowed.
• The final screening assessment was published on August 1, 2009.
