Canadian Pacific's SD90MAC locomotives, numbered in the 9100-9160 series had been in long term storage in Winnipeg, Manitoba for much of the 2010-decade. With three units, the 9129, 9133 and 9138 being scrapped in November 2012 due to errors in preparing them for long term storage. The entire fleet had been put up for sale in November 2012 and again in January 2013 with no offers being made. These units remained stored until the Winter of 2018 when at first 30, then all 58 remaining units entered a rebuild program to be converted into SD70ACUs. In 2021 Canadian Pacific purchased 40 more SD90MAcs from the Union Pacific for further rebuilding into SD70ACu engines.
