It's less than $500,000 a year? That's what the government spent since you and I started this conversation.
It just seems that we're going to tax people on money they haven't actually received and might never receive. We're going to create the administrative nightmare of having to go back to CRA when their client defaults on a payment to say, “Listen, CRA: I know I paid you tax on that money I never made. I can now confirm I'm never going to make it. Can you please give me a refund on that non-existent income?”
Also, the Government of Canada can raise a half a million bucks?
