With the merger between the Aviation Corportation of Canada and Western Canada Airways, along with the financial backing of the two main railways (C.P. and C.N.), the new company had a virtual monopoly of the air transport business in Canada. Three divisions were created: a Western sector, Eastern, and Pacific.
Problems arose with the Western sector as the Post Office Department in Ottawa cut back on airmail expenditures. With the
loss of airmail contracts, the western sector applied to issue a semi-official stamp between Edmonton and Fort McMurray. A year later,
the company also had permission to use the a semi-official stamp between Winnipeg and Cold Lake.
