In Canada, each region has different standards when it comes to film classification. Listed below, are the organasations control classifications for their respective region.

British Columbia Film Classification Office (British Columbia, Yukon and Saskatchewan), Alberta Film Ratings (Alberta, Nunavut and Northwest Territories), Manitoba Film Classification Board (Manitoba), Ontario Film Review Board (Ontario), Régie Du Cinéma Québec (
Québec) and the Maritime Film Classification Board (Nova Scotia, New Brunswick and Prince Edward Island).

Newfoundland has no legislation in place to standardize film classifications, however most theatres will use the ratings provided by the British Columbia Film Classification Office.

On the whole, there are 2 major sets of "ratings".
One is for the English language films while the other is for French language. The French language films are classified under the Québec system, which is also colour coded. It is as follows:

G: Suitable for General Audiences. Little or no sex content and violence.

8+:  Mild violence, language and sexual situations. Appropriate for those aged 8 and above.

13+: Moderate violence, language and sexual content. Those under the age of 13 must be accompanied by an adult.

16+: Strong language, violence and sexual content. Appropriate only for those aged 16 and above.

18+: Restricted to adults aged 18 and over. Can contain extreme violence and graphic sex scenes and nudity. May be pornographic in nature.

The English system is as follows:
C: Works made specifically for children under 8, with no profanity or adult themes. Minimal comedic violence is permitted.

C8: For children aged 8 and over. Little sex and nudity is permitted, as well as low level violence and fantasy horror. No profanity is to be used.

G: Like the "General" rating across the globe, G films can be viewed by the entire family, with low level violence, and no adult themes and profanity.

PG: Parental Guidance recommended. Moderate violence, some bad language, and some sex and nudity scenes (if it is in context) is permitted.

14+: Programming for viewers over the age of 14. 14+ works may contain high level violence and sex scenes, providing it is within context.

18+: This rating allows for strong language, extreme violence and sex scenes. This has occasionally been applied to pornographic works.
Both English and French works have another rating, which is E.

E: E stands for Exempt, and is applied to programs such as news, sports, documentaries, talk shows and music videos.
