Yukon MLAs have unanimously voted to amend the Vital Statistics Act to allow for same-sex parents to both be listed on their children's birth certificates. 

A Whitehorse couple filed a human rights complaint earlier this year after they were told the second mother's name could not be on their son's birth certificate unless she formally adopted the baby.

"I'm very happy to be able to pass the amendments to the Vital Statistics Act so quickly," Health Minister Doug Graham told the legislative assembly.

Graham said the change will be applied retroactively.
