Brown returned to Canada in 1923 and in 1927 was hired as a pilot by
Western Canada Airways (WCA), moving equipment and passengers to northern Manitoba. In the fall of 1929, Brown was intrinsic to a search and rescue mission in which he returned a group of seven men lost in unexplored reaches of the Arctic. In 1930, following WCA's expansion as
Canadian Airways, Brown became superintendent of the company's prairie airmail operations. However, airmail became too expensive and the service was cancelled in 1932, and Brown became a regional chief pilot. With three partners, Brown founded Wings Limited in 1934 and served as its president and operations manager. Canadian Pacific Railway bought the company in 1941, forming
Canadian Pacific Airlines (CPA). Brown spent the next few years working for CPA, taking a leave of absence during WWII to serve as a test pilot for Macdonald Brothers Aircraft in Winnipeg, test flying more than 2,500 aircraft. In 1947, Brown and Milt Ashton, a partner from Wings Limited, purchased their former bush flying operation from CPA as Central Northern Airways (later
Transair). Brown served as its director. He was also a member of the Winnipeg Flying Club, and an executive on the Wartime Pilots' and Observers Association. == Politics ==
