Several sections of the 401 are currently undergoing Planning, Preliminary Design and Class Environmental Assessment (EA) Studies to evaluate the highway's future footprint for the next 75 years, including an eventual eight lanes.
​
As part of the planning process, the Ministry of Transportation (MTO) and the consulting team will be holding two Public Information Centres (PIC) per study to give community members the opportunity to learn about the project and share feedback on proposed alternatives.
​
Several studies are of concern as these areas of the 401 bisect critical ecological corridors within the Frontenac Arch. Public consultations provide concerned citizens the opportunity to get involved and ensure that the planning team considers the ecological health of the region in their decision making processes.
Below are the current planning studies that we encourage you to get involved in.
Gananoque to Mallorytown
The consultation period for this planning study will be opening on October 23, 2025.

This is a particularly critical area as our research indicates that the construction of three wildlife overpasses would reconnect habitats and support safe passage for species such as fishers, red foxes, and black bears. Please visit this page for more information on our recommended solutions.

Kingston to Gananoque
This consultation period for this planning study is currently underway, with the first PIC held on October 2, 2025. The comment period will be open until November 3, 2025.
Within this corridor, Stevenstown Creek, Joyceville Creek, and Grass Creek are vital hydrological and ecological linkages that support both terrestrial and aquatic species. Previous studies note that several species at risk may be present in or near the study area, including Black Tern, Northern Map Turtle, Least Bittern and Gray Ratsnake, species who rely on these habitats and the connectivity that the culverts provide. The rehabilitation of these culverts present key opportunities to enhance connectivity and improve safe passage for wildlife as part of the highway upgrades.
Mallorytown to Brockville
This consultation period for this planning study is currently closed. The first PIC was held on April 23, 2025, with the next PIC scheduled for late Spring 2026.​​

This section of the 401 bisects Jones Creek, a priority wildlife corridor and one of the most intact north-south habitat pathways across the Frontenac Arch. Conversely, this area experiences one of the highest rates of road mortality.​ Inclusion of an underpass would greatly enhance connectivity and provide safe passage for larger wildlife species.
