Democrats retreat to cities. Are Canada's politics different?

In the quarter century since Bill Clinton's anomalous mandate, Democrats have retreated to the cities. See counties won out of a possible 3112:

1992     Bill Clinton      1494
1996     Bill Clinton      1693
2000     Al Gore             642
2006     John Kerry        567
2008     Barack Obama  833
2012     Barack Obama  649
2016     Hillary Clinton  454 (A second source says 489)

The stunning graphic bears study.  Columns are counties.  Column height is population. Column colour is the percent advantage for the party.  Los Angeles county has 10 million citizens favouring Hillary by 25 to 50 % over Donald.  One link is 3D interactive.

What I see in Canada is the same cities/globalist trend-line but zones in Quebec and the Maritimes have their own populist back histories.  We are not immune but have some breathing room to watch the political lab to the south as it goes toxic.  This is a natural phenomenon, arising from the behaviour of complex groups, and it won't be going away any time soon. What is next?
