The 2019 federal budget directed the NCC to refresh existing studies on potential corridors for an additional crossing between Ottawa and Gatineau.
We have completed the refresh of the 2013 technical study on three potential corridors that were previously identified as having the most potential:
- Kettle Island (Corridor 5)
- Lower Duck Island (Corridor 6)
- McLaurin Bay (Corridor 7)
About the refresh
The refresh addresses new transportation data, updated air quality modelling techniques, land use and property plans, and other socio-economic data.
The refresh considered only technical elements of a potential sixth interprovincial crossing. It does not include a recommendation for a specific corridor.
Key findings
Transportation Study
- Major findings remain largely unchanged from previous analysis
- C5 found to attract the most transit trips
- C6 found to attract the most traffic to new bridge as well as away from existing bridges
- C5 found to attract the most truck trips
Noise and Vibration Report
- Consistent with 2013 findings
- C7 to have the least impact
Air Quality Report
- Consistent with 2013 findings
- C5 expected to have the lowest concentration of pollutants, followed by C7 then C6
Land Use and Property Report
- C6 found to impact the least area, marginally followed by C5 and C7
- 2013 report C5 had the smallest area of impact
Economic Development Potential Study
- Consistent with 2013 findings
- C7 has the most potential for new jobs
Fisheries and Aquatic Habitat Report
- Relatively unchanged
Natural Environment Report and Addendum
- C5 and C6 found to have the least constraints
- Both present moderate constraints
Indigenous History Report
- No constraints with any corridor
Next steps
These refreshed technical studies will inform any future considerations of this project. Further planning would include the following:
- an impact evaluation that includes a comprehensive consultation with the public and stakeholders
- work to leverage results of the long-term integrated interprovincial crossing plan
