Legalities regarding firearms for bear safety in wilderness?

Bear spray while hiking is a good plan right. Traveling from Skagway into Canada, I am Canadian, I was asked if I had bear spray. If you have it which is a good idea in that area, they will take it away as considered restricted, go figure. So up the road at Carcross one can replace it if confiscated. Again go figure.

Now if hiking the Chilkoot trail, will bearspray be ceased crossing into Canada?
