Be careful with where they store your data, they might be Canadian, but they might be storing your data in the USA and sharing it with USA companies. Read their terms.
I suggest using software that runs on your computer, like GenuTax, sadly it is windows only.
As far as I am aware, only a single online offer used to encrypt your data, but they removed it when they were bought by WealthSimple, so they could sell your data to third parties.

They are great, most politicians just shove their papers under the door or in the mail. I like the door hanger better!
Sadly, I was not home when they came by. If you are in contact with the organizers, please send my thanks.
