If you are travelling as a group, or if you are traveling alone, taking the bus makes a lot of sense. Ottawa has several bus-friendly transportation options for the traveller.
To catch a major inter-city bus, you need to go to the Central Bus Depot, on Catherine Street. Its south of the downtown and close to the Queensway, and definitely not a walk if you have luggage! Voyageur Colonial (613-238-6668) is the major bus company to points east, west and south. Ottawa is the major connecting point for its buses to southern Ontario (Toronto), eastern Canada (Montreal, Halifax), northern Ontario (Sudbury, Sault Ste Marie, Thunder Bay), and Western Canada (Winnipeg, Ottawa, Vancouver). In Sudbury, the buses connect to Greyhound (1 800 661 8747) for Western Canada. Voyageur drops you off in Toronto at either Scarboro Town Centre, in the east, and downtown, where the main terminal is not far from airport connectors. You can also connect to many cities in the United States in Montreal and Toronto, via Greyhound.
