Panel Upgrade Timeline (Toronto Hydro Coordination)
We know that scheduling a major electrical upgrade often feels like a logistical puzzle for property owners.
You probably want to know exactly how long the power will be off and when the inspector will show up.
Our crews typically complete the physical installation in four to eight hours, though the entire coordination process takes two to four weeks.
Let’s look at the real-world timeline data, what it actually means for your daily routine, and explore a few practical ways to prepare.
What This Guide Covers
Our timeline breakdown covers everything from the initial install day to the ESA final inspection.
You will see exactly how the scheduling works and what to expect during the outage.
1. Typical 1-day install for residential 100A to 200A
We find that moving from a 100A to a 200A panel takes our electricians about four to eight hours on site.
Most Toronto homes built before the 1990s still run on 60A or 100A service. This outdated capacity simply cannot support modern additions like an electric vehicle charger or a high-efficiency heat pump.
Our recent 2026 data shows a standard 200-amp upgrade in Toronto averages between $2,500 and $4,500. This cost fully covers the new equipment, labour, the required permits, and the utility coordination fee.
- Federal Pacific Stab-Lok models.
- Zinsco panels installed from the 1960s to 1980s.
- Old fuse boxes lacking modern breaker technology.
2. Toronto Hydro disconnect and reconnect scheduling (2-week lead time)
We coordinate the essential Toronto Hydro disconnect directly for properties located in the city.
Any upgrade involving a service size change requires the utility to verify the meter base and physically disconnect the power at the street level.
Our team books this disconnect and reconnect on your behalf to minimize your downtime.
A standard service upgrade request currently requires a lead time of two to four weeks for Toronto Hydro to process, reflecting updated 2026 schedules.
| Utility Provider | Coverage Area | Typical 2026 Lead Time |
|---|---|---|
| Toronto Hydro | City of Toronto | 14 to 28 days |
| Alectra Utilities | Mississauga, Vaughan, Markham | 10 to 14 business days |
3. ESA inspection step (5 to 10 days post-install)
We always pull the mandatory Electrical Safety Authority (ESA) permits under our own Licensed Electrical Contractor (LEC) name.
Homeowner-pulled permits transfer liability directly to you and are often not defensible if you ever need to file a home insurance claim.
Our quotes bake the permit and inspection costs right into the flat rate. A legitimate Toronto LEC will never present the ESA fee as a separate, surprise line item.
The final physical inspection typically occurs three to ten business days after the installation is complete, with inspectors arriving between 8:00 a.m. and 4:00 p.m.
- Conductor sizing and breaker coordination.
- Grounding continuity for overall system safety.
- AFCI and GFCI coverage in required living zones.
- Clearance compliance around the newly installed panel.
4. Power-out window (typically 4 to 6 hours)
We work efficiently to ensure your home is only without power for a localized window of four to six hours.
This specific timeframe allows enough room to safely remove the old equipment, mount the modern 200A panel, and make all the necessary circuit connections.
Our experience across the Greater Toronto Area shows that every panel upgrade duration follows a consistent pattern, but specific details always dictate the exact pace.
Replacing a clean, modern panel in North York moves much faster than dealing with a 1960s bungalow setup featuring aluminum wiring and thick plaster walls.
Pro Tip: Schedule your panel upgrade during cooler weather or early in the day. This simple choice minimizes the impact of any heating or cooling downtime while the power remains disconnected.
5. Homeowner prep checklist (food, work-from-home, alarm)
We recommend planning ahead for the scheduled power outage to make your installation day completely stress-free.
A dead laptop battery can ruin a remote workday, so preparation makes a massive difference in your personal comfort.
Our crews handle the heavy technical lifting, but a few simple steps on your end will keep your household running smoothly.
- Charge all laptops, tablets, and mobile devices fully the night before.
- Keep the refrigerator and freezer doors closed to protect perishable food.
- Notify your home security provider about the planned temporary outage.
- Prepare a backup internet connection, like a mobile hotspot, if you work from home.
