The way Trump has acted towards Canada, talking about NAFTA etc, made me think of someone who has an eye for the territories up north...
Quebec separatism is mostly quiet. There's a left/centrist government in Alberta for the first time, reducing provincial tensions between the west and central Canada. Trade links with Europe and Asia have been broadened or are broadening. The economy remains spmewhat tepid but stable.
Meanwhile the U.S. itself has progressed closer and closer into the depths of right wing extremism, and shows no signs of healing.
Harper being so pro-monarchy, insisting on the War of 1812 as being a national foundational myth, trying to assert soverignty in the North seem to be a realization of this identity problem. Also take the current celebrations for the federation's 150th anniversary: the branding completely skips the fact that there were people in the region calling themselves Canadiens for roughly 200 years prior...
Add to that the recent underwhelming documentary on the country's history done by the CBC and the current Premier's own belief that the country has no core identity (being "post-national").
All in all I believe there's a good chance that Canada as you and I know it today will not be around to celebrate another 100 years.
Canada has always been an elitist kleptocracy profiting off shipping out resources -- Laurentian or other elites whose fundamental modus operandi has been to control the process of digging stuff up, cutting it down, pumping it out, or trapping/killing/skinng it... and sending it out of the country while doing the least amount of industry building at home. It's always been the Family Compact, the HBC, CN, CP. A small club of elites. The current Prime Minister is the epitome of it.
Those people are still in charge and not going anywhere. As long as there's something to dig up and sell to the world they'll hold on for dear life.
