UDEC Computer Inc was created by restructuring UDEC Computer Services Inc and amalgamated companies. UDEC Computer Services Inc. was initially founded in 1984 as a privately owned Canadian company. Initially, UDEC's mandate was to provide high quality third party service and warranty repair for computer peripherals and controllers.

In 2008 CYCOM Canada commenced servicing UDEC Computer Services maintenance contracts. However CYCOM Canada and UDEC Computer Inc. have no current business association.

In 1993 UDEC purchased a well known Markham-based, computer module repair and exchange company CMX with an established customer base across Canada and the USA. This highly sophisticated computer repair facility and the expert technical staff also merged with UDEC.

In 1990 UDEC purchased the field service operations of Genamation Inc., a medium-sized 16 year old Canadian computer distributor. Genamation's existing field service and technical staff merged with UDEC.
