Same-sex marriage became legal in Canada in 2003 when a series of court decisions declared that denying the privilege to homosexuals was unconstitutional. The
Civil Marriage Act was approved by the Canadian House of Commons on June 28, 2005, by a margin of 158 to 133 and was subsequently passed by the
Senate of Canada on July 19, 2005, before being given
Royal Assent on July 20, 2005. This law brought the two provinces where such court challenges had not been resolved, Alberta and Prince Edward Island, in line with the rest of the country. The issue remained controversial and Conservative leader
Stephen Harper pledged to revisit the issue with a
free vote should the Conservatives form a government. Harper's party won the greatest number of seats in the
2006 federal election. Harper said that he would address this issue by means of a simple motion to the House as to whether or not the matter should be revisited. If the motion were to pass his government would introduce legislation to change the legal definition of marriage to two opposite sex people, while creating civil unions for same-sex couples; should the motion be defeated, the government will take no further action. ==House of Commons==
