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.
Links to each of the Canadian options are available on ShopCanadianStuff.ca

Tbh I found the same. The one I use has garish colour scheme (which has improved) and initially I thought wtf. But their focus is the bankend, rules,math and logic. In 15 minutes I can have my taxes done and filed online and it only cost me $15 for max 20 filings.
