Pretty much, yes. Montcalm vs Wolfe. Plains of Abraham for the romantically inclined. England vs France. Very old rivalry indeed and much bloodshed. Conservative, Anglicized Toronto with its roast beef & Yorkshire Pudding at the old Park Plaza at Avenue Road & Bloor vs the far more progressive, European and jazzy Montreal which had it all. Center of corporate Canada back then, the NHL itself headquartered in Montreal. The lead up to Expo 67 with then beyond innovative design, then the event itself, throwing a party for the World during Canadas' Centennial. The first MLB franchise awarded outside of the US. The 1976 Olympics....
Toronto wanted all of that & more. So sure, a "rivalry" as Montreal ruled supreme, Toronto ascendant. As hockey in both locales is pretty much a religion, well, at every level, Junior, even amateur tournaments between Quebec & Ontario based teams often very fractious affairs. Our system vs theirs and there was an ugly side to it as well in some instances, nasty examples & cases. That the french were in some ways "inferior" to the english having lost the country, the battle of Trafalgar, Napolean sent packing to rot on Elba.
This is where guys like Don Cherry are coming from. His hero Admiral Horatio Lord Nelson. Quebec in the 40's objecting to Conscription considered cowardly & treasonous by many in Toronto, English Canada. Conn Smythe with his whole "we are Marshall" meme. His Brigade of Sportsmen. Imlach. Ex Army Drill Sarge. Brush cuts one & all & dont talk back. Full Metal Jacket Baby.... Montreal, your doin the Lambada down rue Ste Catherine with a blond on one arm & a red head on the other behind a fabulous Dixie Band, and thats 7 nights a week.
Funny story about Chicago playing in Montreal one night in the mid-60's. Hull & some of the Hawks out partying it up after a game at a bar & Bobby Hull spots Gump Worsley in the parking lot. Goes over as hes starting it to take off and in a loud voice says "where ya goin Gump? C'mon, lets go get laid". Didnt seem to realize or see Gumps wife sitting next to him in the car (or maybe he did, and thought it hilarious to drop kick the Gumpster in the dumpster with the Mrs.).... That was Montreal though. Totally different on some levels but very much the same as Toronto on others.
