From 1980 to 1983, only Canadian actresses were eligible for the award; non-Canadian actresses appearing in Canadian films were instead considered for the separate Genie Award for Best Performance by a Foreign Actress. After 1983, the latter award was discontinued, and both Canadian and foreign actresses were eligible for Best Performance by an Actress in a Leading Role.
