Where you can live and still reach Toronto’s Union Station by public transit in 30 min, 1 h, 1.5 h and 2 h, arriving during the weekday morning peak — subway, streetcar, bus, GO rail and UP Express, plus the walk at each end.
Each band is the area from which you can reach Union Station within that time, arriving during the weekday morning peak. It is computed by routing a grid of points to Union with r5py — real multimodal transit (subway + streetcar + bus + GO + UP) including the walk at each end — and tracing the reachable area, assuming you time your departure to catch service. GO & UP service varies a lot by time of day and several GO lines run peak-direction only, so reach is larger in the morning peak than off-peak. Coordinates and grid are approximate.
