For us, it's hard to imagine what the outcome could be.
We had a greater selection of airlines and destinations prior to joining Canada, but at that time all trans-Atlantic flights had to stop in Newfoundland to re-fuel. So even if Air Canada's relative monopoly is destroyed and that horrible airline is relegated to the trash bin of history where it belongs, we'll never receive the level of service we enjoyed pre-1949 ever again. Also, Gander was the main airport for the entire island back then.
Newspaper ad from 1942:
I imagine the result would be a significant drop in air fares for destinations on the Canadian mainland and a small but still significantly improved selection of international destinations - but, overall, less service at a better price. I'm willing to accept that.
For sure Texas and Norway would be direct flights, as they both account for a huge percentage of the growth at YYT. And, given the success WestJet has had with its direct St. John's-Dublin flight, I imagine that would continue as well.
I also think it's a slight possibility that some international airlines wouldn't have the snobbery of Air Canada and would bring some trans-Atlantic flights down in the Maritimes or Newfoundland to fill them up. It's been annoying as hell having to fly 3.5 hours west to Toronto and then back again to Europe. It more than doubles the distance. Sorry, TO businessmen, a 45-minute stop for you isn't worth more than 7 hours for me.
Cruise lines do it all the time. Disney Cruise Lines just added a stop in St. John's to its Stockholm-NYC run. And that adds way more time to the journey than a little dip to an international airport.

BTW, just for laughs.
Departing: June 16
Returning: June 20
St. John's - Dublin (4 hr 15 mins; Westjet): $743.49
St. John's - Dublin (NON-DIRECT; Air Canada): $2,324.53
St. John's - Toronto (3 hr 26 mins; Westjet): $846.65
St. John's - Toronto (Air Canada): $681.67
However, you can get seat sales that drop to price to $500-$550 for the St. John's-TO flight. I chose the cheapest, non-discounted fares to compare.
