What you should do is call revenue canada and ask for sure but I think as long as you put down her name address and phone number on your tax form that should be enough. Ideally you will have some way to prove what you paid such as a duplicate or cancelled cheque. Since you don't have to include receipts don't be surprised if you get a letter from revenue canada many months from now asking you to verify the amount paid. I thought there was a law that could charge a provider for not providing a receipt but not suggesting that be the first course of action. The phone call is the best place to start. There may even be some info on the revenue canada website itself about how to claim without a receipt since this is a lot more common than it should be.
