A civilian flying club aerodrome 7.4 km south of Moose Jaw, Saskatchewan, became a federal installation just after the outbreak of World War II and was called the RCAF Station Moose Jaw. A new aerodrome was completed in 1941 and the station was the site of the British Commonwealth Air Training Program (BCATP) which used Harvard and Oxford aircraft to train pilots from Commonwealth and other countries. RCAF Moose Jaw was de-commissioned in 1946 and returned to civilian use.

Prince Albert Calvary Pastoral Charge was formed in the mid-1950s, as part of Prince Albert Presbytery and consisting of Calvary United Church.

In 1925 John W. Gibson and his family, wife Martha "Queenie" and sons Sheldon and Murray, moved to Saskatoon and set up a studio at 650 Broadway Avenue specializing in commercial and portrait photography. He also took photos in rural areas. To augment their income during the Depression, Queenie and the boys did amateur photofinishing. Murray joined the firm in 1945, and by 1952 he and Queenie formed a partnership as John W. was in failing health. The studio expanded into photo supplies and moved away from photofinishing.
