Apple Maps can provide routes for both Edmonton Transit System (ETS) buses and Edmonton Light Rail Transit (LRT) trains throughout the Edmonton area, including to and from the Edmonton International Airport.
Apple Maps gained a Transit tab in iOS 9. The feature lags several years behind Google Maps, but Apple's public transportation support is exhaustive, mapping all station entrances and listing departure times. Apple Maps also provides detailed advisories about service interruptions and other changes.
At launch, the feature was limited to Baltimore, Berlin, Boston, Chicago, London, Los Angeles, Mexico City, New York, Philadelphia, San Francisco, Sydney, Toronto, and over 300 cities in China. Since then, Apple has been working to expand support for public transportation to other cities around the world.

Updated: As pointed out by MacRumors reader Creek0512, Apple Maps transit directions have also gone live in Québec City and Ottawa, the capital city of Canada. In Ottawa, OC Transpo buses and O-Train directions are available. In Québec City, RTC bus and Métrobus directions are available.
