Thanks for sharing. Old Montreal is beautiful. In many ways, it's a model for heritage conservation districts. Preserve entire buildings, not just facades. Restore and renovate the buildings, and adapt them to new uses. Invest in streetscapes and public spaces like parks and squares. Restore heritage pavements like granite blocks and bricks. Use small and unobtrusive traffic lights that don't block visual sight lines. It's one of the most interesting historic districts on the continent.
However, I wish that some of the buildings had more prominent signs for their businesses. There are probably heritage restrictions in this regard. Some of the streetscapes (but not all) look sterile and lifeless or like a museum because you can't see any commercial signs for the businesses located in the buildings. Also, most people in the photos look like tourists. It would be better if the district had more of a mix of tourists and locals.
