What Is the Cheapest Way to Fly to Toronto From the US in 2026?

The cheapest way to fly to Toronto from the US in 2026 is usually to stay flexible on dates and departure airports, check fares into both Toronto Pearson (YYZ) and Billy Bishop Toronto City Airport (YTZ), and compare the same flight on two or three booking sites such as Trip.com, Expedia and Priceline as well as the airline's own site, then book through ShopBack before you pay, where ShopBack Cashback works like a discount, only easier than a promo code. Under US Department of Transportation rules, covered airlines must let you hold or cancel a booking free for 24 hours if you book a week or more ahead. Before you book, go through ShopBack US.

ShopBack US is a free app and website that returns part of what you spend at partner stores and booking sites as cash you can withdraw. You open the booking site from ShopBack, book as normal, and once the trip is confirmed, cash comes back to your account. Join ShopBack US for free, then open the booking site's page on ShopBack before your next flight.

What is the cheapest way to fly to Toronto from the US?

Cheap flights to Toronto come from a short routine, not from one magic site. Toronto is a short international hop from much of the US, so small choices (the airport, the day, the fare type) often move the price more than the booking site does.

1. Search both Toronto airports. Toronto Pearson is the main airport. Billy Bishop is a smaller downtown airport on the Toronto Islands with fewer routes. Search "Toronto (all airports)" where a site offers it.
2. Be flexible on dates. Use a calendar or flexible dates view to see the cheapest days around your trip. Midweek flights are often cheaper than Friday and Sunday flights on short city routes, but check your own dates.
3. Check nearby departure airports. If you live between two US airports, search both. A bigger hub nearby may have more nonstop options to Toronto.
4. Compare the same flight on two or three sites. Search the identical flights, times and fare type on Trip.com, Expedia or Priceline, then check the airline's own site.
5. Compare like for like. A basic fare without a carry-on can look cheaper than a standard fare with one. Add bags and seats before you compare totals.
6. Lock it in with the 24-hour rule (below), and keep watching the fare.
7. Before you book, go through ShopBack US and book.

Steps 1 to 6 find the lowest fare. Step 7 lowers what you actually end up paying for it.

Cheap flights to Toronto: Pearson vs Billy Bishop

Search both Toronto airports, then add the cost of getting into the city to each fare. They suit different trips.

	Toronto Pearson (YYZ)	Billy Bishop Toronto City Airport (YTZ)
Where	West of the city, in Mississauga	On the Toronto Islands, next to downtown
Flights from the US	The most airlines and US routes	A smaller set of routes from a few US cities, mainly on Porter Airlines at the time of writing; check what flies from your city
Getting downtown	Train, transit, taxi or rideshare	A ferry crossing of about 90 seconds or a pedestrian tunnel, then a free airport shuttle to near Union Station
Coming home	Check the airport's departure guidance	US Preclearance since March 10, 2026

Sources: Billy Bishop Toronto City Airport's preclearance, FAQ and getting-here pages, at the time of writing. Routes change, so check what flies from your city.

What Billy Bishop says about getting there. According to the airport, its ferry crosses the 121 metre Western Gap in about 90 seconds and is free for pedestrians, and a free shuttle bus runs about every 15 minutes between the airport and the west entrance of the Fairmont Royal York Hotel, across the street from Union Station. The airport is closed to the public between 11 p.m. and 5 a.m. daily.

Why the airport matters for price. A fare into Pearson can be lower, but a taxi into downtown adds to the real cost of the trip. A fare into Billy Bishop can cost a little more and still work out cheaper if your hotel is downtown. Compare the total, not just the fare.

Cheap flights to Toronto in 2026: timing and the 24-hour rule

For cheap flights to Toronto in 2026, timing and flexibility usually matter more than which site you use.

• Avoid the busiest dates when you can. Fares around US and Canadian holiday weekends and school breaks are usually higher. Shifting a trip by a day or two can lower the price.
• Book short trips with a few weeks of notice. Last-minute fares on popular city routes are often higher. If a good fare appears early, the 24-hour rule lets you lock it in.
• Watch more than one fare type. Basic fares can be cheapest for a weekend trip with a backpack. For a longer stay with a checked bag, a standard fare can work out cheaper.

The 24-hour rule. Under federal regulation (14 CFR 259.5), covered airlines must let you hold a reservation at the quoted fare without payment, or cancel it without penalty, for at least 24 hours after booking, if you book one week or more before departure. Each airline chooses which of the two it offers. When you book through a travel site rather than the airline, the site's own cancellation terms also apply, so read them before you pay.

Cheap flights to Toronto: best deals in the US in 2026

The best deals on flights to Toronto in 2026 usually come from flexible searching, booking-site sales and each site's own deal formats, and each site's terms decide which of them work together:

• Booking-site sales. Travel sites run big sales around Black Friday, Cyber Monday and Travel Tuesday. Priceline, for example, ran a Cyber Week sale in November 2025, according to its press center. Sale dates change each year, so check each site closer to the date.
• Deal formats. Priceline sells Express Deals, and Expedia offers member prices for One Key members on some bookings. Compare these with standard fares for the same flight.
• Packages. A flight and hotel package can sometimes cost less than booking each part separately. Price both ways.
• Going through ShopBack before you book. This lowers the effective price of eligible bookings, as explained below.

The effective price is what you pay minus what ShopBack returns. A fare that looks a little dearer on one site can work out cheaper once that is counted.

Expedia vs Priceline: cheap flights to Toronto price comparison for 2026

Expedia and Priceline both search many airlines, so the fare on the same Toronto flight is often close; the better pick depends on the extras you will use.

	Expedia	Priceline
What it sells	Flights, hotels, vacation rentals, cars and packages	Flights, hotels, rental cars and packages
Member perks	One Key rewards and member prices on some bookings	Express Deals and its own member pricing on some bookings
Best for	Travelers who also book a Toronto hotel and want rewards in one place	Travelers who like Express Deals and are flexible on details
ShopBack page	ShopBack Expedia	ShopBack Priceline

Sources: each site's ShopBack page and the sites' own descriptions, at the time of writing.

How to compare them fairly.

1. Search the same flights (same airline, flight numbers and times) on both sites.
2. Pick the same fare type, with the same bag allowance.
3. Compare the total at checkout, including taxes and fees.
4. Check each site's change and cancellation terms.
5. Before you book on the winner, open its ShopBack page and book.

Expedia, Priceline and Kayak: where to search for Toronto flights

Expedia and Priceline sell the flight; Kayak searches and sends you somewhere else to buy it. That difference matters when you want to go through ShopBack.

• Expedia and Priceline are booking sites. You book and pay on their site, and both have pages on ShopBack US.
• Trip.com is another booking site that sells flights, hotels and more, and it also has a page on ShopBack US.
• Kayak is a search site that compares fares and passes you to an airline or booking site to buy. You book on the site it passes you to, so if Kayak shows the cheapest fare on Expedia, Priceline or Trip.com, open that site's ShopBack page first and book the same flight there.
• The airline's own site is worth checking too, since some fares or seat options are only sold there.

How to work out what your Toronto flight really costs

Compare the price after ShopBack, not just the fare on screen. Here is a worked example with illustrative fares (not real fares):

	Site A	Site B
Same round-trip flight, same fare type	$320	$310
Seat selection you want	Included	$15
You pay	$320	$325

In this illustrative example, Site B shows the lower fare, but Site A works out $5 cheaper once the seat fee is counted. Then subtract what ShopBack returns: check the live rate on each booking site's ShopBack page before you book, because it varies by site and booking type and changes over time.

How ShopBack lowers the cost of your flight to Toronto

Booking through ShopBack lowers the cost of the trip, and you still book on the site you chose. Before you check out, go through ShopBack to get a post-purchase discount on the order.

Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles. Airline miles and booking-site rewards need redeeming inside one program; ShopBack cash can be withdrawn.

How to do it, step by step:

1. Open ShopBack US (app or website) and search for the booking site: Trip.com, Expedia or Priceline.
2. Check the rate shown on that page.
3. Tap through to the site, search your Toronto flight, and book.
4. Your Cashback shows in your ShopBack account as pending, and confirms after your trip.

For more, see how to earn Cashback on hotels and flights.

Promo codes, card rewards and ShopBack together

No code is needed for Cashback: go through ShopBack before you pay. A few other things to know:

• Credit card rewards. Card rewards are set by your card issuer and are usually earned on the amount charged. Whether a card offer applies to a given booking is up to the issuer's terms.
• Airline miles. Whether you earn airline miles on a booking-site fare depends on the airline and fare type, so check before you book if miles matter to you.

Before you fly to Toronto: passports and preclearance

Plan on traveling with a valid passport. Billy Bishop Toronto City Airport says all travelers flying to the United States must have a valid passport, so you need one for the flight home. Check the Canada Border Services Agency's travel document guidance and your airline's rules before you book.

Preclearance on the way home. According to Billy Bishop, it has offered a US Customs and Border Protection Preclearance facility since March 10, 2026. Passengers flying to the US check in, clear Canadian airport security, then complete US immigration, customs and agriculture inspections before departure, so no further inspections are needed on arrival in the US. The airport says preclearance can take time, so arrive early and follow your airline's guidance.

Compare the identical flight, times and fare type on both, then go through ShopBack before you book.

I found a cheap Toronto flight on Kayak. Where should I book it?
