It was a lot more helpful when the CCPRN tax workshops were given by seasoned caregivers and not people from revenue canada. Of course they are going to just spout what is written and not let you know all of the extra perks you can claim. But if you do get to ask questions like that you will be told how to do the receipts etc for yourself.

It all comes down in an audit of logic and proof. You have proof in that you have a piece of paper you wrote and dated 3 years ago (assuming you are audited back which they tend to do) that says you bought a puzzle, 2 books and sorting toy at a garage sale for $10. It is a legitimate item in that it falls under supplies-toys and was done at the time of sale/purchase not like an afterthought.
