Canada Tax Questions Answered by Experts
I am not quite following the facts. If you got a letter stating you don't owe any money what is the concern now?
You need a tax lawyer to assist you.
The lawyer has to deal with the government for you and prove that you were not the director during those years even though your former partner neglected to remove your name or perhaps deliberately did that.
But you can prove you were not an owner or a director and so therefore will not be liable at the end of the day.
