Motion picture ratings in Canada are mostly a provincial responsibility, and each province has its own legislation regarding exhibition and admission. For home video purposes, a single Canadian Home Video Rating System rating consisting of an average of the participating provincial ratings is displayed on retail packages, although various provinces may have rules on display and sale, especially for the R and A categories.

There are currently six film classification offices rating movies in Canada, each an agency of a provincial government:

The province of Saskatchewan has a Film and Video Classification Board, but since 1997, it uses ratings provided by British Columbia. There is no compulsory film ratings system in Newfoundland and Labrador, but Maritime Film Classification Board ratings are voluntarily used by some theatres. Of the three Canadian territories, Yukon uses British Columbia ratings, while Nunavut and the Northwest Territories use Alberta ratings.

In the past there was a wide range of rating categories and practices in the various provinces. However, the five rating systems outside Quebec now all use categories and logos derived from the Canadian Home Video Rating System. In general, the categories are:

This system was adopted by Alberta and British Columbia in 1997. Manitoba and Ontario adopted it in 2003 and the Maritimes adopted it in April 2005.

There is also a common stock of Information Pieces ("Frightening Scenes", "Coarse Language", etc.), although different boards may have additional qualifiers.

Each board is responsible for assigning a rating to films, and while most movies will likely obtain the same rating, there can be differences. For instance, the film The Texas Chainsaw Massacre: The Beginning was rated 18A in Alberta, British Columbia and Ontario while Manitoba and the Maritimes gave the film an R and Quebec gave the film a 16+ (it was R in the USA).
