Lights and Power for a New Neighbourhood

The charming and historic town of Unionville in the City of Markham is thriving …and growing. Our client, PowerStream Energy Service, an electricity distribution company owned by the City of Vaughan, the City of Markham and the City of Barrie, retained DPM to design a new underground hydro and streetlight system that could service approximately 800 customers. This new residential subdivision, Upper Unionville Phase 1, is located between 16th Avenue, Madison Heights Boulevard and Brock Avenue in the City of Markham.

DPM’s design for the new subdivision includes 17 kilometres of underground primary hydro cable, 93 pad-mounted transformers and 238 streetlights.

DPM’s Role

  • Preparation of the detailed hydro/streetlight design drawings for the project area
  • Run cable pulling tension calculations
  • Run photometrics for street lighting
  • Run voltage drop calculations
  • Coordination with PowerStream to finalize and approve the design
  • Utility coordination
  • Preparation of IFC (Issued for Construction) work order package and drawings
    for construction


A Key Feature

The new system we designed for PowerStream features spare ducts. The spare ducts installed in the system will save our client both time and money when the aging infrastructure eventually needs to be replaced. However, the families moving into this new Unionville neighbourhood will be enjoying reliable power and street lighting for years to come.
