Five air stations were established for civil flying operations in 1920: •
Halifax, Nova Scotia, a former
US Navy seaplane base responsible for the overhaul of
Curtiss HS-2L flying boats,
fishery and forestry patrols, and aerial photography. •
Roberval, Quebec, a seaplane base on
Lac Saint-Jean responsible primarily for
forestry patrols and surveying. •
Jericho Beach, British Columbia, a seaplane base responsible for fishery, forestry, anti-smuggling patrols. •
Morley, Alberta, a landplane base responsible primarily for forestry patrols. •
Rockcliffe, Ontario, a landplane and seaplane base responsible primarily for photo surveying. Additional stations were added in subsequent years: •
Victoria Beach, Manitoba, established in 1921 as a seaplane base responsible primarily for forestry patrols. •
High River, Alberta, moved from Morley in 1921 due to poor flying weather. • The
Northern Ontario Mobile Unit, a temporary seaplane base operated from boxcars on a
Canadian National Railway siding in
Sioux Lookout, Ontario for the 1921 flying season responsible primarily for forestry patrols. • Temporary seaplane bases at
Whitney, Ontario and
Parry Sound, Ontario for the 1922 flying season, responsible primarily for forestry patrols. ==Members==
