"...Heading up there..." Assuming you're driving, you'll have to pay our licencing fee just to drive through. $25Cdn.($19.07USD as of today). And don't even think about CCW.
Go here and think Option 1. Failing to do so
will result in your arrest, being escorted to the border and turned over to Homeland Security(who will likely charge you with illegally exporting a firearm and ammunition under U.S. law. Which I believe is a U.S. Federal felony.) and likely denied future entry. Thank you for coming and enjoy your stay.
