How to Score Cheap Flights to Canada
Here are proven tips, backed by travel experts and bloggers, to help you pay less for your next flight.
1. Be Flexible
- Change your travel dates by a few days to see significant price drops.
- Consider flying from or into alternative airports, such as Hamilton instead of Toronto, or Abbotsford instead of Vancouver.
2. Use Multiple Tools
- Compare a fare to Canada across several platforms before you book, since the same flight can cost different amounts on each.
- Set up price alerts on multiple sites so a drop on any of them reaches you.
3. Book at the Right Time
- Within North America: 6 to 8 weeks in advance.
- Long-haul international: 2 to 4 months ahead.
- Set an alert rather than checking manually, so a drop reaches you instead of you hunting for it.
4. Watch for Hidden Fees
- Budget airlines may charge for bags, seat selection, or payment methods. Always check the final price before booking.
5. Use Loyalty Programs
- Even if you’re not a frequent flyer, sign up for loyalty programs to earn points and access special deals.
The 11 Best Websites Compared
1. Google Flights
A leading metasearch engine that aggregates flight data from hundreds of airlines and online travel agents behind a fast, intuitive interface. It does not sell tickets; it redirects you to the airline or agent to book. It includes low-cost carriers like Flair and WestJet, which matters on Canadian routes, and its Explore tool suggests cheaper dates or nearby airports.
Pros
- Fast, user-friendly interface
- Price tracking and alerts
- Calendar view and price trend graphs
- Includes Flair and WestJet
- Robust filters for layover length and airline alliance
- Price prediction tool
Cons
- Does not always find the lowest price
- Redirects to external sites where the price can differ
- Limited support, as a metasearch engine
2. Expedia
A major online travel agent where you book flights, hotels, and packages directly, earning One Key Rewards points that stack with airline miles. Its inventory includes Air Canada, WestJet, and Flair, and bundling a flight with a stay often brings the total down on a Canada trip. Flexible date searches, budget filters, and no-change-fee options suit cautious travelers.
Pros
- Direct booking with a large inventory
- One Key Rewards programme
- Flexible date and budget filters
- No-change-fee options
- Reliable support and a strong app
- Bundling savings
Cons
- Booking fees on some itineraries
- Prices can differ from the airline’s own site
- Not a metasearch engine, so it can miss niche deals
3. Kayak
A metasearch engine that compares prices across airlines and agents, then redirects you elsewhere to book. Hacker Fares combine one-way tickets from two different airlines, such as Air Canada out and Delta back, which often beats a single-carrier return. PriceCheck verifies a deal against an itinerary screenshot.
Pros
- Hacker Fares for cross-carrier savings
- PriceCheck for verifying a deal
- Flexible dates and price alerts
- Comprehensive filters for cabin class and layover length
- Strong on cross-border flights
Cons
- Excludes some ultra-low-cost carriers
- Redirect prices can vary
- Some agents add fees at checkout
4. Momondo
A Booking Holdings metasearch engine with an intuitive interface and unusually wide coverage, including budget carriers like Flair and Porter on Canadian routes. Mix & Match combines one-way tickets for savings, though the booking can split across two sites. Visual price trend graphs, filters down to aircraft type, and CO2 emission sorting cover a lot of ground.
Pros
- Visual price graphs
- Mix & Match fares
- Extensive filters, including aircraft type
- Budget carrier coverage
- CO2 emission sorting
Cons
- Mix & Match splits your booking in two
- Can miss some regional carriers
- May redirect to less reliable agents
5. Skiplagged
Skiplagged specializes in hidden-city ticketing: booking a flight that stops in Canada on the way somewhere else, then simply not taking the final leg. On cross-border and international routes this can cut the fare sharply. It is also the riskiest option here, and worth understanding fully before you use it.
Pros
- Hidden-city fares no conventional search will show you
- Simple interface
- Good for one-way or last-minute trips
Cons
- Airlines prohibit hidden-city ticketing in their conditions of carriage
- You cannot check a bag, since it travels to the ticketed final destination
- Skipping a segment normally cancels the rest of the itinerary, including your return
- Frequent flyer accounts have been closed over it
- Limited support if something goes wrong
6. Skyscanner
A top metasearch engine comparing prices across airlines and agents, including Air Canada, WestJet, and Flair. Its Everywhere search shows the cheapest destinations from your departure city, which suits a flexible traveler. Calendar views highlight low-fare dates and price alerts track the drops.
Pros
- Everywhere search for open-ended trips
- Calendar view for the cheapest dates
- Price alerts and strong filters
- Budget carrier coverage
- Well-built app
Cons
- Can miss some regional carriers
- Redirects may add fees
- Prices can change on the booking site
7. Cheapflights
A Booking Holdings metasearch engine built around visual tools: price calendars and fare trend charts. It includes budget airlines like Flair and Porter, and its Smart Value algorithm balances cost against convenience, so a slightly pricier fare with a shorter layover can rank higher. Filters cover layover cities, alliances, and fare policies.
Pros
- Price calendars and fare charts
- Smart Value ranking that weighs cost against convenience
- Budget airline coverage
- Strong filters
- Easy interface
Cons
- Can miss ultra-low-cost carriers
- Third-party redirects
- Limited support, as a metasearch engine
8. Orbitz
An online travel agent offering direct booking of flights, hotels, and packages, with Orbitz Rewards earning Orbucks that you can spend on later travel. Its inventory includes Air Canada and WestJet, and a price guarantee refunds the difference if a cheaper fare appears after you book.
Pros
- Orbitz Rewards and Orbucks
- Direct booking with real support
- Price guarantee
- Flexible date and fare policy filters
- Bundling deals
Cons
- Possible booking fees
- Not a metasearch engine, so it can miss deals
- Prices can exceed booking direct with the airline
9. Travelocity
An Expedia Group agent focused on direct bookings, with a Price Match Guarantee that refunds the difference on a lower fare found within 24 hours. The interface is straightforward, with flexible date searches and filters for budget or changeable tickets, and it bundles well for cross-border trips to Toronto or Montreal.
Pros
- Price Match Guarantee
- Direct booking with support
- Flexible date and budget filters
- Strong on US to Canada routes
- Bundling deals
Cons
- Potential booking fees
- Limited budget carrier coverage
- Less comprehensive than a metasearch engine
10. Priceline
An online travel agent best known for Express Deals, which discount a fare in exchange for hiding the airline and exact times until after you book. Standard searches with flexible dates sit alongside them, its inventory includes Air Canada, and a VIP programme adds further discounts as you book more.
Pros
- Express Deals for lower fares
- Flexible dates and filters
- VIP programme discounts
- Bundling options
- Reliable support
Cons
- Express Deals hide the details until after purchase
- Some booking fees
- Not a metasearch engine, so it can miss deals
11. RatePunk
RatePunk keeps track of what flights from your home airport usually cost, and we alert you when one drops below that price. Deals to Toronto, Vancouver, Montreal, and other Canadian cities show up in the RatePunk app, on the web dashboard, and in deal emails. Every deal gets an AI Deal Score out of 100, and our system checks about 150 million flight prices a day. We don’t sell tickets, so you book the flight with the airline or a travel site.
Pros
- Deals reach you without a search
- Each deal rated by our AI Deal Score
- App filters for destination and travel dates
- Web dashboard shows the regular price next to the deal price
Cons
- A paid membership is needed to see deals
- Tickets are booked on another site
- Each membership covers one home airport
The Bottom Line
There is no single website that is cheapest on every Canadian route. The metasearch engines cast the widest net and are where a search should start. The online travel agents are worth it when you want one itinerary, real support, and rewards points, and are willing to pay a little for that. Skiplagged is a different category, with real savings and real consequences.
The bigger lever is timing, not tooling. Book six to eight weeks out within North America and two to four months out for long-haul, stay flexible on dates and on which airport you fly into, and check the final price with bags included before you commit. Then stop searching and let an alert watch the route for you, because the fares worth having usually appear when you are not looking.
A quick way to choose:
- Searching for a set trip — Start with Google Flights, Skyscanner, or Momondo, which include Flair and other budget carriers on Canadian routes.
- One booking with support and rewards — Expedia and Orbitz let you book directly and earn points toward later travel.
- From the US to Canada — Travelocity covers these routes well, and its Price Match Guarantee applies if you see the fare cheaper within a day.
- A Canada deal you weren’t searching for — RatePunk shows you Toronto, Vancouver, or Montreal deals whenever those fares are lower than normal.
