Canadians will get pardons if they were convicted of possessing marijuana before it was legalised. That means their criminal record for cannabis possession is kept separate from other criminal records - but it doesn't erase the crime. It could still affect people in situations like job applications, travelling abroad and getting houses - and the person who wants a pardon has to apply and pay for it. Some politicians argue that pardoning doesn't go far enough and something called expungement - when all government records of the crime are erased - should happen instead. "We now need to go back and be able to remove the stain that is on the record," the New Democratic Party's Guy Caron said.
