How much would they be to Toronto, Ontario, Canada?

..But for us Canadians , they'd probably be cheaper if you got them at your local home depot...they were about the same price, but in CDN $ (so ~30% cheaper, plus no duty/taxes at the border)
(you can usually find a couple sets keyed the same if you look through them all too..they have a 4 digit key number on the back of the package - find two that match)
regularily
...now back to your regularly scheduled program..
