Which you wouldn't want to check with the CRA either, because the information is often incomplete and updated annually at best.

The CRA even advises that whatever numbers they give you are essentially fugazi, and you should keep your own records because if you make a mistake they will obliterate you with fines.

One of the mottos of the Canadian government is: if you make a mistake because we gave you the wrong information, it is still your fault and you will give us money.

Personal experience, once received a notification from CRA to the effect: "6 months ago we refunded you incorrectly, you owe us, oh by the way we're also charging you a penalty for our mistake.". The amount was not inconsequential but not a problem to remedy. The insult was "we made a mistake and we are punishing you for it".
