Toplessness is legal in Canada for all genders and sexes.
"In 1996, the Ontario court of appeals ruled that women going topless did not imply indecent or sexual behaviour as defined by the Canadian criminal code (R. v. Jacobs, 1996). Similar rulings were made in Saskatchewan in 1998 and in British Columbia in 2000. This chain of events began in 1991 when University of Guelph student Gwen Jacobs, walked in downtown Guelph without a top, thus exposing her breasts. She was arrested and charged with committing an indecent act (DeLonghi, 1992). Jacobs stated that she went topless because it was a hot day and she believed that women should have the same right to go topless as men. She said her behaviour was about empowerment and not just about taking off her top (Canadian Press, 1992). As a result of the Ontario Court of Appeal decision, female toplessness is not considered an indecent act, yet few women go topless in Canada (Murdock, 1996)." Borrowed from a website.
