5. Title, number of pages and langu age(s) of the notified document:  Proposed Order 
Adding Toxic Substances to Schedule 1 to th e Canadian Environmental Protection Act, 
1999 (10 pages, available in English and French).     
6. Description of content:  Canadians depend on chemical substances that are used in 
hundreds of goods, from medicines to computers, fabrics, and fuels.  Unfortunately, some chemical substances can negatively affect our health and environment when released in a 
certain quantity or concentration in the envir onment.  Scientific assessments of the impact 
of human and environmental exposure have dete rmined that a number of these substances 
constitute or may constitute a danger to human  health or to the environment as per the 
criteria set out under section 64 of the Ca nadian Environmental Protection Act, 1999 
(CEPA 1999).  
The objective of the proposed Order Adding  Toxic Substances to Schedule 1 to the 
Canadian Environmental Protection Act, 1999 (hereinafter referred to as the proposed 
Order) made under subsection 90(1) of CEPA 1999, is to add the following substances to 
the List of Toxic Substances in Schedule 1 of CEPA 1999:  
• Methanone, bis[4-(dimethylamino)phenyl]- (C hemical Abstracts Service [CAS] Registry 
No. 90-94-8), hereafter referred to as "Michler's ketone";   G/TBT/N/CAN/314 
Page 2  
 
  Michler’s ketone is a substance not occurring naturally in the environment. It is found 
primarily as a residual in paper colorants remaining from the manufacturing process of some dyes and pigments. It may also be present in textiles and used in inks in pens. Michler’s ketone may also be used in industrial processes such as a component in dry film products and in electronics manufacturing. 
• 2-Butanone, oxime (CAS No. 96-29-7), her eafter referred to as "butanone oxime";  
Butanone oxime is an industrial chemical wide ly used as an anti-skinning agent in the 
formulation of alkyd paints, primers, varnishes,  adhesives and stains for both industrial and 
consumer use. The substance is also used in  Canada as a corrosion inhibitor in industrial 
boilers and water treatment systems, used in the manufacturing process of urethane 
polymers, as a wood preservative and in antifouling marine paints. Butanone oxime may 
also be present in some consumer products and in a number of pesticide products, as well as 
in some adhesives, silicone  sealants and printing inks. 
• Oxirane, (butoxymethyl-) (CAS No. 2426-08-6),  hereafter referred to as "n-butyl glycidyl 
ether".  
The substance n-butyl glycidyl ether is a chemical not reported to occur naturally. In 
Canada, n-butyl glycidyl ether is used prin cipally as a reactive diluent in epoxy resin 
formulations which have applica tions in coatings, adhesives, binders, sealants, fillers and 
resins. 
This addition would enable the development of instruments (which may be regulatory 
and/or non-regulatory) under CEPA 1999 to ma nage the risks posed by these substances. 
7. Objective and rationale, including the natu re of urgent problems where applicable:  
Protection of human health and the environment  
8. Relevant documents:   Canada Gazette, Part I, 1 Ma y 2010, Pages 1058-1067 (available in 
English and French)   
9. Proposed date of adoption:   
 
Proposed date of entry into force:    Normally within 5 to 8 months of publication 
in the Canada Gazette, Part I. 
On the date the measure is adopted. 
10. Final date for comments:  30 June 2010
