A hypothetical Vancouver franchise would do better today business wise and fan support but the price tag just too much I think.... even the Toronto market in the past wasn't a sure thing but they owned by Rogers/Bell
Plus being a small market you'd have to be able to constantly build through the draft because free agents just won't come... look at Toronto 5th largest city in North America and players still brush them off.
Just look at the recent 3 sales. Suns $4 bill, Bucks $3.5 bill, Hornets $3 bill. All USD. The Aquillinis own Rogers Arena. Thus barring someone else being ok with a Celtics/Bruins & Sixers/Flyers arrangement of just being a tenant, that's just too much money for the Aquillinis. The explosion in valuation over the past 7/8 years has been insane. Suns sold for double what Clippers did and what the Rockets did like 2 years after the Clippers.
And now the Sixers are looking to build their own arena after 30 years of being a tenant to the Flyers. And land in Vancouver is insanely expensive. No clue where someone would build another arena.
Only chance of it ever happening is for the Aquillinis to sell the Canucks to someone much wealthier to pay the price tag.
