The Town of Innisfil is undertaking a project to design and reconstruct 25th Sideroad from Big Bay Point Road/13th Line to Innisfil Beach Road. The redesigned corridor adds new features that will:

  • Promote active lifestyles
  • Address traffic concerns
  • Improve the quality of life
  • Address the climate crisis by expanding transportation choices for road users

The proposed features will greatly enhance travel for pedestrians, cyclists, and motorists. By adding sidewalks, cycling facilities, and traffic calming measures, the corridor will support active transportation and improve the safety of road users as Innisfil continues to grow.

The project will be designed and constructed in four phases, splitting the corridor into nine segments. Timelines and phasing are based on the preliminary design and phasing plan, and may be subject to change.
Phase 1 - Detailed Design 2023, Construction 2024
Phase 1 covers a 1.4 km section of roadway from Big Bay Point Road to Mapleview Drive. The project consists of grading and restoration works, drainage improvements including bioswales integrated into the ditches, and a multi-use trail on the east side of the road.
Phase 2 
The project limits of Phase 2 are Mapleview Drive to 10th Line.
Phase 3 
The project limits of Phase 3 are 10th Line to north of William Street.
Phase 4
The project limits of Phase 4 are north of William Street to Innisfil Beach Road.


In 2021, WSP Canada was retained to develop a preliminary design for the project, with a goal to enhance the safety and experience of all road users while expanding transportation options for Innisfil residents. After a thorough public consultation process, the preliminary design was completed in 2022. The design aligns with the Town’s vision to implement roadway improvements that accommodate growth while prioritizing active transportation, safety, and environmental sustainability.
