Narrative:

En route to cyyz, in the vicinity of psi, we noticed oil quantity decreasing toward zero. We referenced oil quantity decreasing checklist. Oil temperature and pressure were normal. Approximately 5 mins later, oil pressure began to decrease. The left oil pressure low light illuminated. We reduced thrust as per the checklist and declared an emergency.
