Devil’s advocate: the better question is what percentage of Canadians will eventually max out their TFSA?

I don’t think it’s a good policy anyway, as the administrative overhead of managing yet another registered investing account (or making TFSA reporting more complicated) is more hassle than it’s worth.

'cause it’s delicious.

You can make your own edible cooking dough. You just have to pasteurize the eggs and flour. If I’m not mistaken, I think the flour is more dangerous than the eggs.

There are even shops which sell edible cookie dough pre-made if you’d prefer the convenience.
