No. You can't buy the Canadian version here in USA.
The USA one is 1 giant piece for the 3rd row equipped 4runners. Meaning if you have the 3rd row mat, and you need to put the 3rd seats up, you are stuck with, WTF do I do with this mat now. Which means you end up trying to roll it up and stick it into the little spot between the seat backs and the gate and pray it doesn't unravel as you drive around. Which also means you have zero truck space.
Hhmmm...if anything, you would think it would be the other way around. Heck, we don't even get the TRD Pro up here!
I'll check my receipt when I get home. Maybe there's a part number I could give you that might help. From the looks of it, from Toyota.ca, they show the exact cargo mat I purchased.
