Re: Tax Back At Toronto Airport ?
Last time I did this I claimed from home. You have set time, I'm sure. You can get a form from any tourist info office and claim back their local and national taxes - just like forign vistors here can claim back VAT.
Doesn't apply to stuff like food items though.
They will give you more info at the tourist office.
The most important thing is to enjoy your life - to be happy - it's all that matters.
