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. For more information on how to cite regulations, see section 5.4 in COAL.
Federal regulations are cited in two different ways depending on how they were published.
1. Regulations published in the Canada Gazette, Part II are cited with a SOR number (which stands for "Statutory Orders and Regulations"), the year they were filed, and a number. Until 1999, only the final two digits of the year are used. After 1999, all four digits of the year are used.
2. Regulations that were included in the 1978 Consolidated Regulations of Canada (CRC) are cited to the CRC with the chapter number. No year is needed.
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 Ontario 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.
