Yeah there is tension all right. But it seldom escalates to violence. The most I have had happen was some teens flipping me the bird and zooming off because I had Ontario plates while driving in Quebec. You’ll get the odd sneer or rudeness from the Francophones but that is it. Once you get some distance from Quebec the tension disappears. A good chunk of the rest of Canada no longer cares if they separate or not. Also many Quebecers are very nice. Not everyone is still carrying a grudge about 1759.
When I lived in Green Bay, everyone pulled for the Montreal Canadiens, not the Chicago Blackhawks. It was a Catholic thing IMO.
I was in grade school when stop sign defacements were news. Then there was Charles de Gaulle stirring up les separatistes in the late 60’s. Public signs in Quebec went French only after that.
In our hotel in Ottawa the elevator announced each floor in English & French. I still have a bottle of `Lemon juice/Jus de citron’ in the fridge.
Anyway, we had a great time in Ottawa, attended a wedding in Cartier Place. Saw the Parliament & the War Memorial, had no idea what would take place there. Everything in walking distance. Watched the locks operate next to the Cartier then climbed up to the heights overlooking the river.
