Narrative:
I swapped into this aircraft and I tested the oxygen mask in accordance with the canadair sopm; and coincident with actuation of the test/reset lever the crew oxy lo press caution message posted. The message disappeared when I released the test/reset lever. Since the gauge indicated approximately 1500 psi; I contacted line maintenance to resolve this discrepancy. Line maintenance discovered that the crew oxygen shut-off valve was in the closed position; meaning that no oxygen was available to the crew masks. The valve was opened and we were returned to service.failure of maintenance up-line to open the crew oxygen shut-off valve. Maintenance: verify task completion. Flight operations: revise the canadair standard operating procedures manual; to include verifying that the crew oxy lo press caution message is not presented during the oxygen mask test. Coincident with issuance of the temporary revision; issue a flight operations alert bulletin for pilot awareness.
