Environmental assessment for electrification complete

Metrolinx has released the environmental assessment for the proposed electrification of the UP Express. You can comment on the plans for the next 30 days.


  • Despite assurances that the diesel trains are low-emission, “air quality within the UP Express corridor will improve” when they are converted to electrical, even accounting for extra the power generation.
    • But the difference might be small. Diesel trains will consume about 140 L of fuel passing through Weston each day.
  • It doesn’t look like the electrification will result in any additional expropriations in Weston.
  • There are plans for a new station in Mount Dennis.
  • Construction will, of course, be irritating, and will last two to three years
  • The Humber River bridge is culturally significant for its history, engineering, and importance to the community.
  • Electric trains will be no noisier than diesel trains. They might be quieter.
