My personal belief–which you should not take as being legal advice which I’m unqualified and not allowed to provide–is that, yes, an individual can form a corporation in Ontario as long as he/she:
Is 18 or older;
Of legally sound mind; and
Not an undischarged bankrupt.
However, an incorporator must be a Canadian resident to be the corporation’s sole officer, shareholder and/or director. I’m pretty sure this is right but recommend you run it by counsel to be sure. Glenn
