Regulations are passed under the authority of a particular statute at either the federal or provincial level. They are published with a citation to the year they were filed, and, like statutes, they are periodically consolidated. Listing the title of the regulation is optional.
Federal regulations are cited as "Statutory Orders and Regulations" (SOR) with the year they were filed, and a number.
Consolidated federal regulations are cited to the "Consolidated Regulations of Canada" (CRC) with a chapter number.
Ontario regulations are cited as "Ontario Regulation" (O Reg) followed by a number and the last two digits of the year in which the regulation was filed.
Consolidated Ontario regulations are cited to the "Revised Regulations of Ontario" (RRO) 1990 (the most recent time regulations were consolidated), and then the regulation number.
As with statutes, a pinpoint reference will refer to a specific section number within the regulation. The pinpoint appears at the end of the citation.
