CRA is running a public consultation on automatic tax filing. You can fill it out here.
Here’s the verbiage about the project
It’s unbelievable that Canada makes people with trivial tax needs jump through so many hoops. If someone is elderly and poor, they need to file taxes to receive their full benefits. That’s a huge barrier to many people.
We have online system here so you can use, say Studio tax, to login to your CRA account and it auto downloads all the documents and prefills the entries.
