Alectra projects

Alectra has the following project underway in Guelph:

Park Avenue


  • 7-71 Park Avenue
  • 232-252 Dublin Street North
  • 76-80 London Road West
  • 215, 221, 223 Glasgow Street North

Nature of the work

  • Electrical system upgrades

Project timeline

  • Construction is expected to begin in May/June 2022 and extend into November 2022.

Details of the work

  • The existing rear-lot overhead pole line between Park Avenue and Dublin Street North will be removed.
  • The pole line between Park Avenue and Glasgow Street North will be removed.
  • These systems will be replaced with a network of underground ducts and pad mounted transformers. The pad mounted transformers will be installed on the roadway and boulevard on Park Avenue.

Impact to residents

A pre-construction survey/inspection of the existing buildings in the construction area will be completed to capture the current condition of the building.

  • Alectra will need to access properties to remove the existing rear-lot pole line.
  • There will be a temporary interruption of power when homes are converted to the new electrical supply.
  • There will be impacts to on-street parking during the day, however it will be available during the evening and overnight.
  • Alectra plans to work on a small portion of the street at a time and then progress further with restoration following immediately behind to minimize the disruption to customers.

There are no plans to remove trees during this work.

  • Currently, Alectra does not plan to remove any trees.
  • Alectra will engage a consultant specializing in tree inventory, assessment and management to prepare a tree inventory and protection plan.
  • An arborist will be onsite when the trenching/excavating takes place to ensure Alectra is following all requirements to protect and save the trees.
  • Alectra will need to prune some of the trees to make sure they are not damaged by construction vehicles during the work.

Why these electrical upgrades are important

  • The existing pole lines have reached the end of their life cycle and need to be replaced.
  • There are access and maintenance issues with a pole line located in the rear yard.
  • Alectra Utilities will replace the rear yard system with an underground front yard system that aligns with current standards and will allow better access for maintenance purposes.
  • Underground electrical systems are less prone to outages during extreme weather events like ice and wind storms, and this work will ensure the efficient service of the infrastructure to continue to deliver reliable electricity service to customers.
