- Construction of a rail guideway offset within the corridor during construction to accommodate a temporary diversion track and a temporary rail diamond;
- Modification of an existing at-grade road crossing at Wallace Avenue to become a road under rail grade separation;
- Enhancements to the public realm, including artwork on the structure cladding and new pedestrian and cyclist routes; and
- Provisions for future electrification implemented within upgraded rail infrastructure to accommodate future electrified GO train service.
