Ah, Option C Printout... Many people actually wonder what it is.
Eventhough it doesn't look like beeelythe is going to need it, I will explain this in case somebody with Option C related questions uses the search function.
The Option C Printout is not something you automatically receive when you file taxes. It can be ordered at CRA by calling them at the following number: 1-800-959-8281 .
You tell the person on the phone that you need an Option C Printout and they will know what to do.
What they in fact do is, on their computer they select not Option A, not Option B, but Option C. Then they hit the "Printout" button. Hence the name. Seriously!

After you ordered this miraculous piece of paper, it takes up to 10 working days to arrive. Usually less.
