Cost of a 200 Amp Electrical Service in Montreal in 2026
The equipment, access, utility coordination and other factors that determine the cost of a 200 A service upgrade.
How much does a 200 A service upgrade cost in Montreal?
A 200 A upgrade is more than a panel replacement. It can involve the meter base, mast, service conductors, grounding, main equipment and coordination with Hydro-Québec. For that reason, a reliable price cannot be based on the panel photo alone.
As a planning reference, many standard residential projects fall in the low-to-mid thousands of dollars before tax, but unusual access, relocation, underground service or major corrections can increase the cost. Lumineau Électrique provides a detailed quote after confirming the scope.
Main factors that affect the quote
- Existing configuration: overhead and underground services require different work.
- Location: moving the meter or panel can require longer conductors and building repairs.
- Mast and attachment: height, clearance and condition must be evaluated.
- Number of circuits: transferring and identifying a large panel takes more time.
- Grounding and bonding: older installations may require corrections.
- Access and finishing: ceilings, walls, exterior cladding and restricted electrical rooms affect labour.
- Utility requirements: some work depends on Hydro-Québec scheduling or modifications.
Why the load calculation still matters
An owner may request 200 A for an EV charger or heat pump even though load management could solve the immediate need. Conversely, a renovation involving electric heating, a second dwelling and vehicle charging may genuinely justify the upgrade. The calculation should come before the final design.
What a clear quote should show
The quote should identify the service size, main equipment, panel and breaker allowance, utility coordination, known corrections, warranty and exclusions. Ask whether drywall, painting, trenching or asbestos-related work is included.
Prepare for the visit
Provide photos of the meter, mast, panel and route between them. List upcoming electrical equipment and mention whether access is available above ceilings or through unfinished spaces. This information helps the electrician prepare an accurate visit and reduces surprises.
A properly planned 200 A upgrade should meet today’s needs while leaving a clear and maintainable installation for future work.
