Here’s a diagram showing all the Canadian tax software options, almost everything is made by a Canadian company except two of the most commonly used.
Please stop using turboTax and H&R Block, you’ll likely save quite a bit of money by switching to one of the Canadian owned options too. (H&R Block charges $49.98 for a typical couple, Studio Tax charges $17.50 for up to 10 returns). GenuTax is completely free to use.

There are some free ones in Canada, but even the paid ones are cheap I paid $15 for a license, it gives you 20 filings. I did 4 people so less than $5 each and the speed vs paper forms is worth it. However I hear Canada is moving to the system where they may do the taxes for you and you sign it.
