April 3 (Reuters) - Trans Mountain's expanded oil

pipeline system will start commercial operations on May 1, the

Canadian company said on Wednesday.

"Trans Mountain anticipates providing service for all

contracted volumes in the month of May," it said.

With the appropriate approvals from the Canada Energy

Regulator (CER) and completion of remaining construction

activity, Trans Mountain will commence transporting crude oil on

the expanded pipeline system, the company said.

"After commencement of operation of the project, Trans

Mountain will continue cleanup, reclamation, road and civil

work."

The company had said earlier that it will finish

constructing the final segment of its Canadian oil pipeline

expansion in April.
