According to a survey from H&R Block, 22 per cent of Canadians have yet to file their tax return. We spoke with H&R Block tax expert Yannick Lemay about what could happen if you file your taxes late in Canada. There are also government benefits that Canadians can only apply for after they've filed their tax return. Lemay stresses that Canadians can still get penalized even if they don't owe taxes. However, if they owe taxes, they'll still need to pay them by April 30.
