The flight crew elected to complete a precautionary engine shut down on the no.1 engine. The flight crew declared an emergency and advised Winnipeg Center that they were shutting down the no,1 engine due to low oil pressure. They executed the Engine Fail/Fire/Shutdown Quick Reference Handbook checklist and shutdown the no.1 engine.
