One of the leading lawyers in the fight to legalize same sex marriage is eagerly awaiting the release of a stamp marking marriage equality.

Douglas Elliott, a lawyer born and raised in Elliot Lake, said he's thrilled one of the new stamps commemorating Canada's 150th birthday pays tribute to the legalization of same sex marriage.

“I never would have guessed when I was a kid that something I did, something I contributed to, would be considered so important our country that it would end up on a stamp and that makes me very proud,” he said.

The agency unveiled the stamp in Toronto at a local centre that serves as a hub for the city's LGBTQ community.

The maple-leaf-shaped stamp shows an image of a rainbow flag and the words "marriage equality" in both French and English.

Canada Post is issuing 10 special stamps to honour key moments in Canada's 150-year history.

It says the day in 2005 when same-sex marriage became legal across the country is one of the milestones that have shaped Canada.

The stamp, along with the other nine commemorating moments such as Expo67 and the creation of the Canadarm, will be available on June 1.
