Louisville is about to get a direct link to Canada for the first time in years. Air Canada will launch nonstop flights from Toronto Pearson (YYZ) to Louisville Muhammad Ali International Airport (SDF) starting Wednesday, April 28, 2027 — the airline's first service to the Kentucky city since 2002.
The route will run four times a week (Mondays, Wednesdays, Thursdays and Sundays) on Air Canada Express, operated by Jazz Aviation with 76-seat CRJ900s. Departure from Toronto is at 2:00 PM, landing at 3:35 PM local time, with the return leaving Louisville at 4:10 PM and arriving back in Toronto at 5:37 PM. At 431 nautical miles each way, it sits among the shorter US routes Air Canada flies from its biggest hub — shorter than services to Cleveland, Detroit, Pittsburgh, Cincinnati or Boston.
The story is bigger than one route. Louisville's airport currently has no international passenger operations at all — the last were lost back in 2012 with Bahamasair and Vision Airlines. Air Canada's arrival restores a cross-border option for a city better known for UPS freight than passenger jets.
Who's it for? Partly business travellers, partly Kentuckians wanting an easy way into Air Canada's global network. Local demand is modest — around 16,300 round-trip passengers flew the Toronto-Louisville city pair indirectly in 2025, mostly connecting through Chicago, Detroit and Atlanta — so connectivity through Toronto Pearson is the real product here. The mid-afternoon departure lines up well with Air Canada's US departures bank and works for Louisville's top long-haul market, London, though not for most same-day arrivals from Asia or Europe. Fares on the market have historically run high for the distance: an average of about US$302 one-way in 2025, versus $194 on Toronto-New York LaGuardia — so a nonstop competitor could shake that up.
The wider picture: by May 2027, Air Canada plans roughly 215 daily departures to the US from eight Canadian airports, serving 44 American cities. Louisville joins the short list of sub-daily routes, alongside Fort Myers, New Orleans and San Antonio.
For travellers, the takeaway is simple: from late April 2027, Kentucky's biggest city gets a one-stop-free path to Toronto and, from there, onward across Canada and to Europe — no detour through a US hub required.
