The disruption is concentrated between Lawrence West and Wilson stations, where trains are expected to operate on a single track. Northbound and southbound services will share the remaining track while crews complete the work.
That arrangement is likely to slow journeys during the Monday morning commute, when workers and football supporters could be travelling through the same corridor. The report says the work is intended to remove several reduced-speed zones before tournament demand increases.
For passengers, the practical warning is simple: a normal journey may no longer provide enough margin.
The report says shuttle buses will operate between Lawrence West and Wilson to help passengers navigate the affected section. TTC staff are also expected to be available at stations to guide customers while the temporary service pattern is in place.
Commuters should consider:
The 25-minute delay warning is especially important for supporters with fixed arrival times, including those heading to fan zones, transport hubs or match-related events.
The timing gives Toronto a chance to complete essential maintenance before the World Cup brings larger crowds and more unfamiliar travellers onto the network. Finishing the work now could reduce the risk of speed restrictions becoming a wider issue once matchday traffic builds.
The next storyline is whether Line 1 returns to a more reliable service before Friday’s fixture. For commuters and supporters alike, the immediate advice remains clear: plan ahead, expect slower journeys and leave room for the unexpected.
