Speed limit zone boundaries updated on Hwys 403, 404, 406, QEW, 407 East, 412, 418 and QEW Link

Plain-language summary · AI-assisted

Several stretches of Ontario provincial highways have had their speed-limit zone boundaries redefined. On Hwy 403, the Mississauga-to-Oakville reduced-speed segment is renumbered and its description clarified; on Hwy 404, the reduced-speed zone now runs from Hwy 401 in Toronto all the way to East Gwillimbury, replacing a shorter York Region–only description. On Hwy 406, the reduced-speed corridor is extended to St. Catharines (from the CN Railway overpass) replacing the previous Thorold reference points, and a new lower-speed segment is added between St. Catharines and the Niagara Regional Road 38 overpass. The Queen Elizabeth Way gains two additional reduced-speed segments—one near Niagara Falls/Fort Erie and one between Oakville and Burlington—while existing segments are realigned to new reference points. On Hwys 407 East, 412 and 418, and the QEW Link, existing Part 1 reduced-speed entries are moved into a new Part 0.1 category. Operators of commercial vehicles and anyone responsible for fleet speed compliance on these corridors should review the updated geographic descriptions to confirm which speed limit applies to their routes.
