John C. Munro Hamilton International Airport (YHM) sits just west of the city and serves as a lower-cost alternative to Toronto Pearson, about an hour's drive east. WestJet and seasonal carriers operate flights to various Canadian destinations, and the airport handles a significant volume of cargo traffic.
For travelers, Hamilton is worth considering if you can find a cheaper fare -- the smaller terminal means shorter queues and less hassle. Ground transport into Toronto is available by GO bus and rental car.
