Should Canada load up on nuclear weapons?

Since Rump and his gang of thugs think they are the ultimate power on the Western Hemisphere, and are using their military to take things they want, maybe Canada should have some nuclear weapons for defence too?
It has always been unnecessary for us to have them since the US were our best friends and we gave them basically free reign over our country, but now that they are not friendly to us, and clearly they are NOT, maybe we should reconsider?
