Toronto's Underground Labyrinth

The conversation highlights the significance of pedestrian tunnels in urban development, with one user stating, "I love these little 'reveals' of 'secret architecture'." Participants emphasize that such networks enhance city livability, particularly in the context of climate change and evolving transportation needs.
