A new law recently passed that says if one of your parents were born in Canada, you are automatically a citizen retroactive to the date of your birth.
This effects a couple of big-name wrestlers, as Dwayne "The Rock" Johnson's dad and Carlito's dad were born in Canada, thus, with this new law, making both officially citzens of Canada.
While both have successful enough careers that this shouldn't matter to them, the new law does now mean both could go to Canada for free health care.
