Two heterosexual Canadian men are to tie the knot to enjoy the tax benefits of being a married couple.

Bill Dalrymple, 56, and best friend Bryan Pinn, 65, are taking advantage of Canada's new same-sex marriage legislation.

"I think it's a hoot," Mr Pinn told the Ottawa Sun.

But the two, both previously married to women, insist there is a serious issue behind the stunt.

"There are significant tax implications that we don't think the government has thought through," Mr Pinn said.

Mr Dalrymple has been to see a lawyer already and there are no laws in marriage that define sexual preference.

The 'couple' have still to set the date.
