In General
In 1987 the Uniform Law Conference agreed that the Canadian legislative drafting conventions should be bilingual and should reflect the practice of the drafters in both languages. The Drafting Conventions are the result.

Sullivan (available in Vancouver and regional libraries), p. 613-624. It includes information on the divisions and arrangement of an act, drafting principles, and language.
