Spotted this on Youtube earlier in the day:

Apparently the museum isn't open to the public but this plane spotter managed to capture some glimpses at the museum. Would be curious to learn more about the museum and how one could access it.

Side note : The YouTuber also has a variety of plane spotting videos primarily out of YUL, YQB and YMX.

Safe Travels,
