(Reuters) - Unifor union said on Friday its members at Shell's Scotford refinery in Canada have applied to the Alberta labor regulator for a strike vote later this month after rejecting a mediator's terms of settlement related to compensation.

The Scotford complex at Alberta consists of a bitumen upgrader, oil refinery, chemicals plant and a carbon capture and storage facility.

The upgrader has a capacity of 320,000 barrels of oil equivalent per day of diluted bitumen, according to the company.

The union said its Local 530-A members rejected the mediator's recommendations since it would have kept the compensation of refinery workers at Scotford "well-below industry standards".

Shell did not immediately respond to a Reuters request for comment.
