So I decided to investigate this. I looked at the schedules for Friday, May 26th 2023 on Air Canada, Westjet and Porter, for departures from YYZ and YTZ to YOW and YUL. Wanted to look far enough out to discount the current issues. I then took the scheduled aircraft and the seat counts from Wikipedia to get a rough idea of how many seats are offered on each city pair. Here's what the schedules look like:
(Excuse the formatting. I have no idea how to do up tables here.)
| AC | WS | PD |
YYZ-YOW | 17 x A223 | 5 x Q400 | |
| | 1 x B738 | |
YTZ-YOW | 4 x Q400 | | 12 x Q400 |
YYZ-YUL | 1 x E175 | 5 x Q400 | |
| 15 x A223 | 1 x B73G | |
| 1 x A321 | | |
| 1 x A333 | | |
YTZ-YUL | 14 x Q400 | | 12 x Q400 |
Here's what the total seat counts look like on each city pair:
| AC | WS | PD |
Toronto-Ottawa | 2641 | 564 | 936 |
Toronto-Montreal | 3710 | 524 | 936 |
If you look at the above, you'll notice that the airlines are scheduling about 25% more seats to Montreal than Ottawa. But it's specifically one carrier that is Montreal focused: Air Canada. They have over 52% more flights to Montreal and 40% more seats. But a large chunk (about a quarter) of the 40% more seats they send to Montreal is literally one aircraft: the A330-300 they are sending there. That's highly likely a repositioning flight that they want to make some money on. For both Westjet and Porter, Ottawa and Montreal are equally important in both the number of flights and the number of seats offered.
I also look at the number of departures on VIA from Union to Ottawa and Montreal. VIA is planning on sending 8 trains to Ottawa and 6 trains to Montreal that day. So even here, Ottawa is actually slightly more important than Montreal.
The idea that Montreal is so much more important as a destination for travelers from Toronto is a myth. It's on par with Ottawa. And the difference in seat counts between Montreal and Ottawa certainly doesn't line up with the population differential between those two cities. It's highly likely a large chunk of the flights and extra seats that Air Canada offers to Montreal is a function of them being a network carrier and needing to shuttle travelers back and forth between YYZ and YUL to make connections at those hubs. It's not entirely about origin-destination demand between Toronto and Montreal.
The routine whining here about Toronto-Montreal travel times certainly leaves that impression that there's people who think that way.
What's the problem with doing that? Nobody is suggesting that this is a primary goal of HFR. Broadly improving travel times is a goal. But from the beginning they've always had other goals that were paramount. Reliability, capacity and frequency are at the top of the list. A secondary benefit of efforts to improve those things is faster travel time. And nobody has suggested that this secondary benefit will be evenly applied.
