Tips Tuesday: When Did Older Ontario Acts Come Into Force?
Generally, if an act does not have any explicitly stated coming in force provisions, it comes into force on the date of Royal Assent. There are, however, exceptions.
For the period after December 31, 1918 and before July 25, 2007, any Ontario act that did not have explicitly stated coming in force provisions did not come into force on Royal Assent. Instead, depending on the date that they received Royal Assent, the coming into force provisions were as follows:
- Acts that received Royal Assent between January 1, 1919 and April 13, 1925 came into force 60 days after Royal Assent.
- Acts that received Royal Assent between April 14, 1925 and December 31, 1936 came into force 60 days “after the day of the prorogation of the Session of the Legislature at which the Act was passed or after the day of signification”.
- Acts that received Royal Assent between January 1, 1937 and July 24, 2007 came into force on the latter of 60 days after Royal Assent or 60 days after the prorogation of the session of the Legislature at which the Act was passed.

This tip is based on a recent discussion on the CALL-ACBD forums. Many thanks to Jen Brubacher for the suggestion and to the staff of the Great Library for the very helpful blog post on the subject.
