We had a similar connection in February. We had to de-ice here and while my memory is muddy I think we were an hour late leaving YYC. We are trusted travellers but still had to rush through YVR, almost ran at one point, but made it as boarding was taking place. We had no time to grab anything but at that point you’re just happy you made the plane and will happily fork over $20 for plane food.
I hate tight winter connections and avoid them or try and overnight if it’s feasible. It adds to the trip but the cost is outweighed by a lower stress experience. You’ll likely have no issues and you’re unlikely to be the only ones on your flight with the same connection.
Be mindful of any snacks you bring, remember you’re limited in what can go across customs and if in doubt declare it or ask the customs guys.
