Map: Where same-sex couples can marry
Before the Criminal Law Amendment Act was passed in 1969, homosexuality was a criminal offence in Canada, as it remains to this day in many other countries.
Four decades later, Canada and nine other countries — Argentina, Belgium, Iceland, The Netherlands, Norway, Portugal, Spain, South Africa and Sweden — have granted marriage rights to same-sex couples on an equal footing with heterosexuals.
Yet many other countries, as well as most American states, have laws restricting access to same-sex marriage.
Here are some key dates in the story:
May 8, 2012: North Carolina, U.S.
Voters in the state approve a constitutional amendment defining marriage solely as a union between a man and a woman.
March 1, 2012: Maryland, U.S.
Gov. Martin O'Malley signs into law a bill that would legalize same-sex marriage. The law won't take effect until January 2013 though, and risks repeal if opponents gather enough signatures to force a referendum in November.
Feb. 17, 2012: New Jersey, U.S.
Gov. Chris Christie vetoes a bill allowing same-sex marriage in New Jersey. His decision came a day after the state Assembly passed the bill. Christie, a Republican who opposes same-sex marriage, had vowed "very swift action" once the bill reached his desk.
Feb. 13, 2012: Washington, U.S.
Washington state Governor Chris Gregoire signs a gay marriage measure into law, effective in June. However, if opponents gather enough signatures to force a referendum, it might not take effect until November at the earliest.
Feb. 7, 2012: California, U.S.
The 9th U.S. Circuit Court of Appeals rules that Proposition 8, a 2008 provision that banned gay marriage in California, is unconstitutional. This likely means that Proposition 8, which was approved by voters, will likely move to the U.S. Supreme Court.
Jan. 12, 2012: Canada
The federal government says it is considering how to make divorce possible for same-sex couples who had to come to Canada to get married. Thousands of gays and lesbians who could not marry in the country where they live have travelled to Canada seeking a legal marriage. But Canada's divorce laws don't allow people who haven't lived in Canada for at least a year to end their marriage.
Jan. 1, 2012: Delaware and Hawaii, U.S.
These two American states begin recognizing civil unions between same-sex partners.

A U.S. Federal Court judge overturns Proposition 8, California's controversial same-sex marriage ban.
July 15, 2010: Argentina

- New Hampshire
- New York.
July 7, 2010: Hawaii, U.S.
Hawaii's governor vetoes legislation that would have allowed same-sex civil unions. Gov. Linda Lingle told a news conference the bill would have allowed "same-sex marriage by another name."
A law allowing same-sex marriage comes into force in Iceland. That same day, Icelandic Prime Minister Johanna Sigurdardottir weds her longtime partner, Jonina Leosdottir.
Same-sex marriage becomes legal in Portugal, almost three weeks after the country's conservative president signed a gay-marriage bill into law. President Anibal Cavaco Silva said he did not veto the bill because the majority liberal lawmakers would only overturn his decision.
March 4, 2010: Mexico City, Mexico
A law allowing same-sex marriages in the city comes into effect.
Dec. 2, 2009: New York state, U.S.
The New York state senate rejects a same-sex marriage bill that the main assembly had passed six months earlier.
Nov. 4, 2009: Maine, U.S.
Maine voters repeal a state law that would have allowed same-sex couples to wed. State lawmakers had voted in favour of same-sex marriage the previous May.

Several couples rushed to tie the knot on April 27, the day the ruling took effect.
Sweden's parliament votes 226-22 to recognize same-sex marriage.
Sweden gave gay couples legal "partnership" rights in the mid-1990s, and allowed them to adopt children from 2002. The new law, which comes into force May 1, lets homosexuals wed in either a civil or religious ceremony, though individual churches can opt out.
A law comes into effect allowing gay couples the right to marry, adopt and undergo artificial insemination.
Nov. 4, 2008: Various U.S. states
A 52 per cent majority of California voters support Proposition 8, a ballot initiative that defines marriage in the state constitution as a union between a man and a woman. The vote reversed a May 2007 California Supreme Court decision to strike down the state's ban on same-sex marriage.
Six months after the vote, the California Supreme Court upheld the Proposition 8 ban. But it also ruled that the roughly 18,000 existing same-sex marriages carried out in the state before it came into effect can stand.
Amendments to ban gay marriage are also approved in Arizona and Florida. Arkansas voters approve a measure banning unmarried couples from serving as adoptive or foster parents. Supporters of the Arkansas measure make it clear that gays and lesbians are their main target.

Nov. 7, 2006: The U.S.
