Early Works - Construction Activities
Early Works are the initiatives or projects that take place early in the construction process to lay the foundation for many of the construction activities to follow. The Early Works projects associated with Highway 413 are identified in the Highway 413 Act, 2024. These Early Works projects are located in areas where engineering design and field investigations have progressed, and were chosen by the MTO because they are either in areas that are, or were previously disturbed, and where the likelihood of environmental impacts is low. Some Early Works are also located in areas that have been identified by local municipalities for additional infrastructure improvements.
Highway 413 Early Works projects include:
- Early Works Project #1: Embankment at 401/407 ETR/413 Interchange
- Early Works Project #2: Highway 10/Hurontario Street Resurfacing & Underpass
- Early Works Project #3: Bovaird Drive Underpass.
Additional Early Works projects may be explored as part of the framework established in the Highway 413 Act, 2024.
Early Works Project #1: Embankment at 401/407 ETR/413 Interchange
Early Works Project #1 began in Summer 2025.
This Project includes the construction of an embankment to support a future connection from Highway 401 westbound to Highway 413 northbound and Highway 407 southbound. The scope of work includes the grading work within the northeast quadrant of the Highway 401/407 ETR interchange.
Work to be completed: Placement of advance fill.
Anticipated impact: No impact to pedestrians, active transportation or traffic.
Early Works Project #2: Highway 10/Hurontario Street Resurfacing & Underpass
The Resurfacing portion of Early Works Project #2 began in Summer 2025. Construction on the Underpass is scheduled to begin in 2026.
The resurfacing portion of Early Works #2 includes the resurfacing of Highway 10/Hurontario Street between Old School Road and King Street. The Underpass contract will include design and construction of a bridge on Highway 10 over the future Highway 413. A temporary detour will be built during construction.
Work to be completed: Resurfacing of Highway 10/Hurontario Street between Old School Road and King Street.
Anticipated impact: Utility relocation and necessary pavement rehabilitation.
More Information
Environmental and engineering studies inform the design for this Project. Furthermore, MTO will assess environmental impacts associated with the construction of Early Works and implement mitigation measures, as appropriate.
The ministry will also obtain any permits and authorizations, if required, and will satisfy any Duty to Consult obligations with respect to Early Works.
As part of our commitment to keeping communities informed, construction notices will be issued to nearby residents, businesses, municipalities, and Indigenous communities, outlining upcoming activities, expected impacts (such as noise, traffic, or access changes), timelines, and contact information for questions or concerns. These notices are also available below.
In accordance with Special Provision No. 199F33, notices will be distributed to the first row of residences located at Steeles Avenue and Tenth Line. This Special Provision outlines the requirements for controlling noise generated by the Contractor’s operations. Noise constraints in noise-sensitive areas will be followed to minimize disruptions to nearby residents.
