Depends who your writing at the CBSA, I've received both phone calls and emails from them. If anyone does take the risk of importing on their own, and do legally abide to declare their purchases while entering back into Ontario (Which is always the safer way) Be polite, don't be an ass at anytime, make sure the weapons locked in the trunk, or even better if you have (and you should) a lock box, put the newly bought, still packaged toy in there - it'll show responsible shipping on your part after purchasing.
I mean it's all common sense but some lack it.
Warchild - Awesome work man

as always is more than nice to see a retailer go that extra mile for their customers. I know it helps your sales out, but very few states side places have done something like this for us.
cheers.
