The 2026 Hazel McCallion Line construction is changing how drivers move along parts of Hurontario Street. Impacts can vary by location and construction phase, particularly where crews are completing track, utility and intersection work.
Drivers should expect temporary lane reductions, slower traffic, restricted turns, intersection closures and changing traffic signals. Available lanes and travel times may shift as work progresses, so a route that is accessible one week may look different the next.
Before travelling, check the latest Metrolinx construction notices and allow extra time, especially during peak periods. If you regularly drive the Hurontario corridor for work, school, appointments or property visits, build flexibility into your schedule and watch for posted detours and updated traffic controls.
As a Hurontario-area real estate agent who drives the corridor every week, I’m sharing this reminder to help neighbours plan with fewer surprises. Save this post, share it with someone who uses Hurontario and follow for more practical Mississauga neighbourhood updates.
