Canadian border agents have a message for Americans looking to visit their country: leave your firearms at home.

According to WGRZ, gun seizures across Canada were up nearly 175-percent from 2012 to 2016; and about 91-percent of those were from U.S. citizens.

In August of last year, the Canada Border Services Agency (CBSA) felt the need to launch a formal campaign reminding Americans of Canada’s firearm laws.

“It is strongly recommended that you not carry your firearm when traveling to Canada and/or transiting through Canada to reach another US destination,” the agency wrote. “However, should you choose to travel with your firearms, you must declare all firearms in your possession at the first Canadian designated port of entry. You must also have all the necessary permits and have your firearm appropriately stored.”

“We welcome our US neighbours in Canada – to make your journey more pleasant, travel light and always remember to declare all goods with you,” CBSA concluded.

In other words: Just don’t bring your guns to Canada.

Unfortunately, it looks like Americans need another reminder.

So far, border patrol agents have seized 70 undeclared firearms in 2017, leading to 22 charges – and that’s just from international bridges in Western New York.

Unsurprisingly, firearms aren’t the only weapons that are prohibited. On its website, CBSA has a lengthy list of items you cannot bring into the country, including, but certainly not limited to, most knives, mace or pepper spray, nunchakus, and taser or stun guns.

Simply put, use common sense and your trip across our Northern border should go just fine.
