Spring 2026 Fare Patterns: When to Book
Toronto domestic fares follow a distinct U-curve through the March–May window:
- Late February – early March (5–7 weeks out): Lowest fares. Toronto–Vancouver and Toronto–Montreal economy fares start at CAD $149 one-way
- Third week of March: Corporate travel season kicks in. Fares rise 18–25% week-over-week
- Mid-April – early May: Easter travel (April 12–21, 2026) combined with conference season creates the spring peak
- Third week of May onward: Fares normalize
Aviation Weekly’s Q4 2025 report confirmed Canadian domestic business routes average CAD $287 in spring — 31% cheaper than summer peak. Spring is the single best value window for corporate travel.

The country’s busiest business route is where all three carriers compete head-to-head.
- Air Canada: 12–15 daily flights, 787 service on select routes. Spacious business cabin, but economy fares run highest at CAD $320–$580
- WestJet: 8–10 daily flights, primarily 737 MAX. Most competitive pricing at CAD $220–$380 and includes a free checked bag for standard economy
- Porter: 4–5 daily flights, E195-E2 aircraft. Free WiFi on all flights and complimentary baggage make it strong value at CAD $250–$420

Which Airline Covers Your Route?

Frequently Asked Questions
Q1: Do spring flights from Toronto experience more delays?
Per Nav Canada’s 2025 on-time performance report, March–April departure punctuality at Pearson sits at 74%, primarily due to Great Lakes weather patterns and spring turbulence. Air Canada leads at 78%, Porter at 72%, and WestJet at 69%. Build in a 90-minute buffer for connections.
Q2: Basic Economy vs. Standard Economy — what’s the business traveler call?
If your itinerary is flexible, Basic can work. But corporate travel plans change — missed that client meeting? Basic fares on Air Canada and WestJet are non-refundable and non-changeable. Standard Economy adds CAD $30–60 per ticket for a full change capability. For business travel, that flexibility almost always pays off.
Q3: Is Porter’s free WiFi actually useful for business?
Porter is the only Canadian carrier offering complimentary WiFi across its entire domestic network. For a traveler spending 2–3 hours responding to emails or joining video calls mid-flight, that connectivity turns dead time into productive hours. For frequent corporate travelers (50+ flights per year), that’s 15–20 hours reclaimed annually.
Q4: Does WestJet’s baggage policy make a real difference?
Since 2025, WestJet standard economy includes a free first checked bag (23kg). Air Canada’s basic economy charges CAD $35–60 for the same bag. For travelers hauling trade show samples, presentation materials, or multiple devices, WestJet’s policy saves CAD $35–120 per round trip.
Q5: What’s the single best booking tip for spring 2026?
5–7 weeks before departure. Our historical fare tracking consistently shows this window delivers the lowest average fares with the most seat availability. The exception: Easter week (April 12–21, 2026) requires 8–10 weeks advance booking, as business and leisure demand collide.
Bottom Line
- Route coverage → Air Canada: 72 domestic cities, highest frequency on thin routes
- Price-sensitive → WestJet: Consistently lowest fares, free checked bag
- Eastern Canada + connectivity → Porter: Toronto–Montreal/Ottawa dominant, reliable free WiFi
