What's the timeline for getting a Toronto Hydro meter upgrade when going from 100 amp to 200 amp service?

Toronto Hydro meter upgrades for 100A to 200A service typically take 2-4 weeks from application to completion, but this can extend to 6-8 weeks during peak demand periods (spring/summer construction season).

The timeline depends on whether you need just a meter base upgrade or a complete service entrance replacement. If your existing service entrance cable from the street is already rated for 200A (which is common in homes built after 1970), Toronto Hydro only needs to swap the meter base and possibly upgrade the connection hardware. However, if you have older 100A service entrance cable, Toronto Hydro must run new cable from the transformer to your home, which takes longer and requires street work coordination.

The process works in coordination with your licensed electrician's work. Your electrician handles everything from the meter base inward — installing the new 200A panel, running the service entrance conductors from the meter to the panel, and ensuring all interior wiring meets code. Toronto Hydro handles everything from the meter base outward — the meter itself, the service entrance cable to the street, and the connection to their distribution system.

Here's the typical timeline breakdown: Your electrician applies for the ESA permit and coordinates with Toronto Hydro simultaneously. Toronto Hydro schedules the disconnect (turning off your power) so your electrician can safely install the new meter base and panel. Once your electrician completes the interior work and passes ESA inspection, Toronto Hydro returns to install the new meter and restore power. The actual power outage is usually 4-8 hours for the electrical work, then another 1-2 hours when Toronto Hydro reconnects.

Seasonal timing significantly affects Toronto Hydro scheduling. Spring through early fall is peak construction season in the GTA, and Toronto Hydro's crews are handling hundreds of service upgrades weekly. Winter scheduling is typically faster — 2-3 weeks versus 4-6 weeks in summer. Ice storm season (December through March) can cause delays if emergency power restoration takes priority over scheduled upgrades.

Condo and townhouse projects face additional complications. If you're in a stacked townhouse or condo with shared electrical infrastructure, Toronto Hydro may require engineering studies and building management coordination, extending the timeline to 8-12 weeks. Some older condo buildings have centralized electrical distribution that makes individual unit service upgrades impossible without major building infrastructure work.

Cost considerations affect timing as well. If Toronto Hydro determines that transformer upgrades or new underground cable installation is needed to support your 200A service, they may charge upgrade fees ranging from $1,000-$5,000+ and extend the timeline to 3-6 months for major infrastructure work. This is more common in older Toronto neighbourhoods where the electrical grid was designed for lower residential loads.

To minimize delays, have your electrician coordinate the Toronto Hydro application early in your project planning. Don't wait until your panel upgrade is scheduled — Toronto Hydro needs lead time for crew scheduling and material ordering. Your electrician should contact Toronto Hydro's New Connections department at 416-542-8000 as soon as you decide to proceed with the upgrade.

Winter ice storm preparedness is driving many GTA panel upgrades right now. After the 2013 ice storm left 300,000+ Toronto Hydro customers without power for up to 10 days, many homeowners are upgrading to 200A service to support whole-home generators and backup power systems. This seasonal demand surge can extend Toronto Hydro scheduling, so plan accordingly if your upgrade is motivated by generator installation.
