S.A.F.E., a business parented by the Salmon Arm Farmers' Exchange, was the first retail co-operative store in Salmon Arm. When its buildings on Front Street and Shuswap Avenue were destroyed by fire in 1956, the business viability was threatened. At a special meeting , November 21st, 1959, it was resolved to liquidate the assets to the newly formed Shuswap Consumers' Co-operative Association which was incorporated in 1958.
The 1960s was a decade of operational disappointments for the new association and at a special membership meeting in January 1970, amalgamation with the Revelstoke and Shuswap Consumers' Co-operative was presented.
On September 1st, 1971, Shuswap Consumers' Co-operative Association, by special resolution, became Mainline Co-operative.
The next five years realized sufficient growth to encourage the association to consider expansion. Feasibility studies were done and in 1976, the decision was made to build and develop a shopping mall on the perimeter of Salmon Arm.
On September 15, 1977, the Mainline Co-operative opened the Cedarvale Centre at the corner of 10th Street S.W. and 10th Avenue S.W. It operated at this location until 1986 when it closed its doors.
