Air Georgian LTd. was formed in 1984 and their HQ is located at Pearson International Airport, as is their maintenance facilities.
Their commercial contract with Air Canada works very much like Air Canada Expresss (Jazz), which i blogged about a few posts ago.
Air Canada Alliance fly from Montreal, Toronto, Halifax and Calgary to 22 US & Canadian destinations.
In regards to Air Canada Alliance (now flying under the Express banner), the fleet consists of Beechcraft 1900D.
This is a small aircraft. But not as small as a Cessna 172, which i have been on and is the smallest aircraft i have flown in.
