As major disruptions on the Toronto public transit system, including shutdowns of subway and streetcar services, caused havoc for downtown commuters on Tuesday morning, some managed to document the chaos on social media.

Transit users packed into stations and replacement shuttlebuses, and long lines clogged sidewalks and underground pedestrian tunnels.

Images and video show crowds of commuters struggling to reach their destinations.

The Toronto Transit Commission said a fire at a hydro vault that caused the delays has since been extinguished.
