Highway 410 as part of the 400-series network

Highway 410 is a 400-Series Highway in Ontario, Canada that connects Highway 401 and Highway 403 to Toronto's northern suburbs, specifically Brampton and Caledon. Its total length is 11.5 km.

Notable about Highway 410 is the 4-level interchange with 401 and 403 which includes a spectacular flyover ramp from 401 eastbound to 410 northbound. From 401-403 to Steeles Avenue, Highway 410 has a wide grass median with the capacity to add 2 lanes per direction.

Ontario Premier Bill Davis, who was known as "Brampton Billy," initiated Highway 410 during his administration. The first step in the 1970s was redirecting of Highway 403's (Mississauga section) eastern terminus towards Highway 401 instead of having it continue towards Highway 427 as originally planned. Highway 410 was then added to the 401-403 junction as a partial interchange with Highway 401 (eastbound only) and the rest of Highway 410 was constructed as a two-lane freeway. By the early 1980s, the northern part of Highway 410 from Clark Boulevard to Bovaird Drive was a limited-access 4 lane expressway; Clark Boulevard and Queen Street were the original interchanges at the time.

In the late eighties and early 1990s, Highway 410 was expanded to its current form concurrent with the construction of Highway 407. The freeway was widenened to 6 lanes south of Clark Boulevard, with much of the work involving the twinning of the existing carraigeway which was later redesignated as the northbound lanes. High-mast lighting was installed and new interchanges were added with Courtneypark Drive and Derry Road; the latter which was designed to accommodate the Highway 407 "clove-stack" junction undergoing construction nearby. In the late 1990s, Highway 410 was widened from 4 to 6 lanes north of Clark Boulevard.

The MTO planned in the late 1990s for Highway 410 to replace the Highway 403 designation for the latter's Missisauga segment, after deciding that the Missisauga-Hamilton gap would be built as the toll Highway 407 instead of a Highway 403 extension. This was later rejected since this could potentially confuse motorists accustomed to the original number which had been in use since 1982.

As of 2006, a northerly extension of Highway 410 (to Highway 10 just north of the Caledon/Brampton border) is in the design and construction stages. Currently, the route north from Bovaird Drive to Sandalwood Parkway in north Brampton has been graded, and the Sandalwood overpass completed. It had been announced by former Ontario Transportation Minister Harinder Takhar that the extension of the highway would resume in mid-May. This extension to Highway 10 would be split into phases, Phase 2 and Phase 3. Phase 2 would be the section from Bovaird Dr. to Mayfield Rd.; Phase 3 being the section from Mayfield Rd. to Highway 10. Certain residents in the Valleywood Subdivision of Caledon are concerned about the extension, for some of their homes may be as close as 65 metres to the planned extension.

Ultimately, in the future, Highway 410 has been speculated to continue on to Orangeville, Shelburne and Owen Sound.
