How long is the flight from the UK to Toronto?

About 7 hours 50 minutes to 8 hours direct from London to Toronto Pearson. The return leg to the UK is usually a little shorter thanks to the jet stream. It's one of the shorter transatlantic long-haul routes, which helps keep fares competitive.

Which UK airports have direct flights to Toronto in 2026?

Direct flights run from London Heathrow (Air Canada, BA), London Gatwick (Air Transat), Manchester (Air Transat), and Glasgow (WestJet, resuming for summer 2026). From other UK airports you'll connect via a UK hub, a European hub, or a US city — compare a connecting fare from your local airport against a positioning trip to London.

Do UK passport holders need a visa for Canada in 2026?

No visa, but you must apply for an Electronic Travel Authorisation (eTA) before you fly. The eTA is a quick online application with a small fee (CAD 7), usually approved within minutes, and is valid for up to five years or until your passport expires. Apply through the official Government of Canada website — avoid third-party sites that charge a markup. Your passport must be valid for the duration of your stay.

How far in advance should I book a UK to Toronto flight?

For the summer peak (June-August), fall foliage season (late September-October) and Christmas, book 3-5 months ahead. For the cheaper winter and spring shoulder, 8-12 weeks is usually enough. Transatlantic fares to Toronto reward earlier booking than short-haul Europe does, and summer is the busiest window.

What is the cheapest month to fly to Toronto from the UK?

January, February and March (excluding half-term) are usually the cheapest, with off-peak returns often £300-£450 — though Toronto winters are very cold. The most expensive are July and August (summer peak), the fall foliage season, Christmas/New Year, and Canadian Thanksgiving in October. May and early June offer a good balance of pleasant weather and lower fares.

Is it cheaper to fly direct or one-stop to Toronto?

Direct is usually both faster and competitively priced from London given the number of carriers, so there's rarely a strong reason to connect from London. From regional UK airports, a one-stop routing via a European or US hub, or a domestic connection to a direct gateway, can be cheaper than positioning to London. Note that connecting via the US adds US entry requirements (ESTA) even in transit, so a direct or via-Europe routing is simpler.

How much baggage can I take to Toronto from the UK?

It varies by airline and fare. Air Canada and BA include a checked bag on standard economy fares but their cheapest 'Basic'/'Economy Basic' fares are hand-luggage only. Air Transat's fares vary by branded tier, with a bag on higher tiers. WestJet's cheapest fares are typically carry-on only with paid checked bags. Always check the fare type and add any bag online in advance, never at the airport.

Can I do Niagara Falls from Toronto?

Yes — Niagara Falls is about 130km from Toronto, roughly 1.5-2 hours by road or a train-plus-connection, and is one of the most popular day trips from the city. Many visitors combine Toronto with Niagara. Fly into Toronto Pearson, base yourself in the city, and day-trip or overnight to the Falls.

How much should I budget for a Toronto flight in 2026?

As a planning figure: budget £300-£450 return for an off-peak (winter/shoulder) economy fare, £450-£700 for a summer or standard fare with a checked bag, and £700-£1,100+ for peak summer, fall foliage or Christmas. Always compare the all-in price including baggage, not just the headline fare.

When is the best time to visit Toronto weather-wise?

Late spring to early autumn (May-October) is the most comfortable, with warm summers and a spectacular fall foliage season in late September-October. Winters (December-March) are very cold and snowy, which keeps fares low but suits city-and-indoor trips or those wanting Canadian winter activities. May, June and September balance good weather with lower fares than peak July-August.

Is WestJet's new Glasgow-Toronto flight worth it for Scottish travellers?

Yes, potentially — WestJet resumes direct Glasgow-Toronto for summer 2026 on modern Boeing 737 MAX aircraft, giving Scottish travellers a direct route without connecting through London or a US hub, plus onward WestJet connections across Canada. Compare its all-in fare (baggage is often extra on the cheapest fares) against a connecting option, but for many Scots the time saved makes it the obvious pick.

How much baggage does each airline include, and what does extra cost?

Air Canada and BA include a checked bag on standard fares but not on their cheapest Basic fares; Air Transat and WestJet vary by fare tier. Extra checked bags on transatlantic routes typically cost £50-£100+ each way, and are always cheaper booked online in advance than at the airport. Check your fare's allowance before comparing headline prices.

Should I fly to Toronto or another Canadian city?

Toronto is Canada's largest city and busiest UK gateway, with the most direct flights and usually the best fares, plus onward domestic connections across Canada. For western Canada (Vancouver, Calgary) or Montreal, direct or one-stop options exist too, but Toronto is the default choice for eastern Canada, Niagara and as a hub. Compare based on your final destination.

Do I need an ESTA if I connect through the US to Toronto?

Yes — if your routing connects through a US airport, you'll need an approved US ESTA even just to transit, because the US has no international transit zone. To avoid that extra step and cost, choose a direct flight or a routing via a European hub (or Dublin) instead. Always check the routing before booking a connecting fare.

Should I book directly with the airline or through a comparison site?

Compare first, then book wherever shows the genuinely lowest all-in price including baggage. A live comparison search shows Air Canada, Air Transat, BA and WestJet direct options alongside any one-stop routings from all your local airports — the fastest way to find the best value for your exact dates.

Airline-by-airline comparison (2026)

Air Transat — the value leader

Typical fare 2026: £300-£600 return, direct from Gatwick and Manchester. Pros: Usually the cheapest direct fares to Toronto, with a leisure-focused product and departures from two UK airports. Cons: Baggage and extras vary by branded fare tier — check what's included before comparing on headline price.

Air Canada — the flag carrier

Typical fare 2026: £400-£750 return, direct from Heathrow. Pros: Multiple daily flights, the widest onward domestic network across Canada, a bag on standard fares, Aeroplan miles. Cons: Cheapest "Basic" fares are hand-luggage only; higher headline fare than Air Transat.

British Airways — direct from Heathrow

Typical fare 2026: £420-£780 return. Pros: Avios earning, a bag on standard fares, strong schedule from Heathrow. Cons: "Basic" fares are cabin-only; pricier than Air Transat.

WestJet — new Glasgow direct for summer 2026

Typical fare 2026: £350-£650 return. Pros: Resumes direct Glasgow-Toronto for summer 2026 on modern 737 MAX aircraft — a direct route for Scottish travellers with onward Canadian connections. Cons: Cheapest fares are typically carry-on only with paid checked bags — check the fare.

The honest read: for the lowest direct fare from London, Air Transat. For a bag, more frequencies and onward domestic connections, Air Canada or BA. For Scottish travellers, WestJet's new Glasgow direct is a strong option. Compare the all-in price with baggage.

Direct vs one-stop

From London and Glasgow, direct is usually both faster and competitively priced given the carriers on the route — there's rarely a strong reason to connect. From regional UK airports, a one-stop routing via a European hub, or a domestic connection to a direct gateway, can be cheaper than positioning to London.

One important caveat: connecting via a US airport requires a US ESTA even in transit, because the US has no international transit zone — an extra step and cost. To keep it simple, choose a direct flight or a routing via a European hub. Compare the routing, not just the price.

UK airport comparison

London Heathrow (Air Canada, BA) and Gatwick (Air Transat) have the most Toronto choice, Manchester has Air Transat direct, and Glasgow gains WestJet direct for summer 2026. From other UK airports, compare a connecting fare from your local airport against the cost and hassle of positioning to a direct gateway before defaulting to London.

Price bands by month for 2026

Round-trip economy, UK to Toronto, one adult. Representative ranges to plan against, not live quotes.

Month 2026	Typical return fare	Notes
January – March	£300-£500	Cheapest; very cold Toronto winter
April	£350-£550	Spring shoulder, good value
May – June	£400-£650	Pleasant weather, rising demand
July – August	£600-£1,000	Summer peak
September (early)	£450-£700	Prices easing
Late Sept – October	£500-£800	Fall foliage season + Canadian Thanksgiving
November	£350-£600	Good-value late autumn
December (early)	£400-£650	Building to Christmas
December (late)	£700-£1,100+	Christmas/New Year peak

The pattern follows the usual transatlantic shape — see our cheapest month to fly from the UK roundup — with Toronto-specific peaks around summer, the fall foliage season and Canadian Thanksgiving (October), plus Christmas.

Baggage compared, honestly

Airline	Economy checked bag	Notes
Air Canada	Included on standard; "Basic" cabin-only	Check the fare tier
British Airways	Included on standard; "Basic" cabin-only	Check the fare tier
Air Transat	Varies by branded fare tier	Read the fare rules
WestJet	Cheapest fares carry-on only; bags paid	Add bags in advance

The rule that saves the most: check what your fare includes and add any bag online in advance — transatlantic airport bag fees are steep (£50-£100+ each way). A cheap Air Transat or WestJet fare plus a checked bag can approach an Air Canada or BA fare that already includes one, so compare the total, not the headline.

The Canada eTA you need (UK passport holders, 2026)

UK travellers flying to Canada need an approved Electronic Travel Authorisation (eTA) before boarding:

Apply online through the official Government of Canada website — approval is usually within minutes, but apply well ahead to be safe.
The fee is a small CAD 7, and the eTA is valid for up to five years (or until your passport expires), covering multiple trips.
Avoid third-party sites that charge a markup for what is a cheap official process.
Your passport must be valid for the duration of your stay.

Always check the current rules on the UK government's Canada travel advice before booking.

The booking windows that actually save money

Summer (Jun-Aug), fall foliage (late Sep-Oct), Christmas: Book 3-5 months ahead — the busiest windows.
Canadian Thanksgiving (October): Book 3-4 months ahead — a demand spike.
Winter/spring shoulder (Jan-Apr, Nov): Book 8-12 weeks ahead — the cheapest fares.
Direct vs one-stop: Re-check both close to booking — the gap changes with demand.

Set a price alert for your dates and lock in when a fare drops below your threshold.

Toronto Pearson to downtown

The UP Express train runs from Toronto Pearson (YYZ) to downtown Union Station in about 25 minutes, very frequently — the fastest and best-value option. There are also airport buses and the TTC transit system, and a taxi or ride-hail takes 30-50 minutes for considerably more. The UP Express is the clear pick for most travellers. Once you've sorted the flight and transfer, our best Toronto hotels 2026 guide covers where to base yourself.

Common mistakes UK-Toronto travellers make

Forgetting the eTA. You can't board without an approved eTA — apply online in advance (and use the official site).
Connecting via the US without realising you need an ESTA. US transit requires a US ESTA — choose a direct or via-Europe routing to avoid it.
Judging fares on the headline price. A cheap Air Transat or WestJet fare plus a checked bag can match an Air Canada or BA fare that includes one.
Leaving a summer or fall-foliage booking late. These peak fast — book 3-5 months ahead.
Overlooking WestJet's new Glasgow direct. For Scottish travellers it can beat connecting through London.
Adding baggage at the airport. Always add it online in advance on transatlantic routes.
Missing the winter/spring value window. Fares are lowest then, if you don't mind the cold.
