3 zones--domestic, US-bound, and non-US international. Both of the Priority Pass lounges are in the non-US international zone, and therefore cannot be accessed unless one is departing from the international zone. Someone in the Canada forum may be able to explain if it is possible to go into the non-US international zone when departing on a US-bound flight.
This is exactly the reason. If you are flying to USA, those flights are in own area since you do CBP pre-clearance at YUL instead of at arrival airport in USA. As a result, you can't access those lounges located in the non-USA international portion of the airport or domestic portion.
