Route details & model limits
The Hazel McCallion Line’s 18 km, 19-stop core project is under construction between Port Credit GO and Brampton Gateway. This atlas shows only its Mississauga alignment, including the City Centre spur. The downtown loop is a separate extension in planning and design.
The core project includes 16 stops in Mississauga.
Continuous colour guides make each route easy to follow: green marks the Lakeshore West, Milton and Kitchener GO corridors. Blue marks the Transitway, including its mixed-traffic Highway 403 connection between Erin Mills and City Centre. The coloured routes follow the model’s physical levels and pass behind buildings and bridges. Below-ground sections are hidden by the ground; neutral tracks show the physical model. Existing transit remains visible in every scenario; the gold Hazel McCallion Line appears in construction and future views.
City railway and Transitway mapping, current GO schedules and community-mapped HML tracks are reconciled at their joins. The City Centre flyover is included. Vertical profiles, inferred second-track offsets and track symbols are illustrative; they are not final engineering alignments. No opening date is assumed. The separate downtown extension is described here without inventing a final track layout.
