Intuit (and any other company allowed to offer NETFILE services) is required to offer a free tax filing option for individuals. The problem is they're allowed to upsell as much as they want, so you have to be careful that they'll absolutely try to sell you some service that you don't need (i.e. audit insurance on a basic T-4 only filing).

For the most part, I have not had a problem using the free service, though you do need to know how to fill out any forms that aren't part of their default wizard.

That being said, if your tax filing is 100% just confirming information the government already knows, then that should just be done for you. I would expect to get correspondence via MyCRA/lettermail (ideally both) that lists what forms from whom were submitted, their final calculations and a notice that it would be finalized on April 30th unless a supplementary return is filed (i.e. un-filed income, deductions etc).

Like, some of it is just silly; to claim disability on a dependent, I have to submit a form that the government sent me, which was submitted by the doctor who provided the diagnosis - to the government. It's not even that department A isn't talking to department B; it's a form submitted to CRA!
