If Canada and US are in Africa and their borders where set by Europeans based on shares of diamonds, coal, gas, silver, gold or oil which is now shared by Shell or BP and you don't share ethnic groups, religions, traditions and you have 100x more ethnic groups than countries... then no. Not like in Canada-US. Did you know that some of those borders where made by Stalin just to provoke them, let them kill each other, provide them weaponry, so they could easily use their natural resources?
