Cheap Flights from Shannon to Toronto

Summer and the weeks around Christmas are the expensive stretch on this route, when holiday traffic pushes fares up and seats go early; Canadian Thanksgiving in October can tighten things too. If your dates are fixed inside those weeks, book as far ahead as the calendar allows. Outside them the picture softens: early autumn is steady, and the fares shown here run from September to March, with November as the cheapest point in the range. Midweek departures usually undercut Friday and Sunday, and a midweek return keeps the connecting itinerary cheaper. March is the last month with prices on this page, so treat it as your planning horizon.

Start with the connections — there are no direct flights on this route. Aer Lingus, Eurowings Discover and United Airlines each build the trip around a stop in their own network, which adds a layover, a second boarding and some schedule risk: a late first leg puts pressure on the second. What's included differs more than the routing. Aer Lingus and United are full-service carriers, with cabin baggage and meals on long sectors as standard, checked bags depending on the fare. Eurowings Discover is the leisure option, with leaner basic fares — checked bags, seat choice and meals can become extras. Compare total cost with baggage included, not the headline fare alone.

Before you land, sort your Canadian entry paperwork: visitors from Ireland generally need an electronic travel authorisation, approved online well before departure. Then note which airport you're arriving at, because Toronto has two. Pearson International is the main gateway, well out from downtown; a dedicated express train, buses and taxis cover the trip, so leave generous time at rush hour. Billy Bishop City Airport sits on an island right beside the centre — you cross by a short tunnel or a ferry, and hotels sit within walking distance of the mainland dock. Check which airport your last leg names, and plan that final stretch before you take off.

Country facts: Wikidata

• Every option here is connecting — keep both legs on one ticket; with separate tickets, a missed connection is yours to fix.
• If two separate tickets are unavoidable, leave a wide gap between flights and expect no rebooking from either side.
• Eurowings Discover fares can exclude checked bags — price baggage into the total before comparing with Aer Lingus or United.
• Toronto has two arrival airports, Pearson International and Billy Bishop City — check which one you land at.
• Sort Canada's electronic travel authorisation online before departure; approval is quick, but not instant.
• November is the low-fare month here, while December and the summer weeks run high, so flexible dates pay off.
