La Presse/ Montréal le 23 août 2016;
CBSA (Canada Border Services Agency);  
«...It is strongly discouraged (Americans) to transport your firearm when traveling to Canada or that you are passing to another American destination. Canada's firearms laws are VERY CLEAR;
Not declaring a gun can cause a seizure, fines, legal action...
and make you INADMISSIBLE to Canada !
Your vehicle may also BE SEIZED and, if so, you will have to pay a fine to get it back."

Got it guys ?...“I-N-A-D-M-I-S-S-I-B-L-E” to Canada !
So Keep your American “Ssshhhhittttt” Out of US !
