I have just been doing this manually by going through Google flights
https://www.google.com/travel/flights and looking at the schedules for each of those markets. I regularly follow the schedules so I already have an idea of what they looked like in 2025 in order to compare them to 2026.
Vancouver (YVR) - WestJet have gone from offering no flights in 2025 to offering a daily flight for most of the 2026 summer season. Air Canada have a daily Vancouver flight from early May to the end of October which is similar to the 2025 season. Air Canada did offer double daily service in September and October in 2025, but this was an add-on later on in the season. This doesn’t currently look like it is offered for 2026, although it was announced very late in the season in 2025 so who knows if it may happen again
Edmonton (YEG) - WestJet have gone from offering one flight a day in 2025 to offering double daily service throughout the 2026 summer season. Air Canada don’t fly this route.
Calgary (YYC) - WestJet fly this route four times daily for 2026, which is identical to their 2025 season. Air Canada no longer fly this route.
Winnipeg (YWG) - WestJet have increased their frequency on this route from one daily to double daily for the majority of the 2026 summer season. Air Canada do not fly this route.
Toronto (YYZ) - WestJet have increased their frequency on this route from three daily flights in 2025 to 4 daily flights for the 2026 summer season. Air Canada will fly this route from 8 to 10 times daily depending on the day for the whole 2026 summer season. This is an increase from 2025 when they generally flew 8 times daily on this route. Porter will fly this route four times daily in the summer season for 2026, which is identical to their 2025 schedule. Flair Airlines will fly this route up to three times daily for the summer 2026 season which is an increase over 2025 where they generally flew the route twice daily.
Much of the increased WestJet flights are aimed at tying in with their ever increasing European flights out of Halifax. For the 2026 season, they are adding Lisbon, Copenhagen and Madrid. These new destinations will be added to their current roster, which includes Amsterdam, Dublin, Edinburgh, London Gatwick, Paris and Barcelona. They seem to be creating a model similar to Icelandair with their Reykjavík hub were they funnel passengers through Halifax from Western Canada to Europe. This was aided with the introduction of the new pre-clearance facility built at Halifax Stanfield International Airport.
