Commercial Electrical Panel Upgrades & Replacements
A commercial panel that trips under normal load, cannot support new equipment, or is flagged during a fire inspection is a business problem, not just an electrical one. EZ Smart Electric upgrades and replaces commercial electrical panels across the GTA, sized to your actual load, not a guess.
Signs a Commercial Panel Needs Upgrading
- Breakers trip when equipment runs together.
- No room for new circuits for a renovation, new equipment, or an EV charger.
- An aging or recalled panel brand flagged during an inspection.
- Planned expansion or tenant improvement that increases the electrical load.
Sizing a Panel for Commercial Load
Commercial load calculations account for continuous equipment loads, HVAC, and code-required demand factors differently than residential work. We run a proper load calculation before recommending panel size, not a flat upsell to the largest available service.
Why Commercial Clients Choose EZ Smart
We are a licensed, ESA-registered electrical contractor with a Master Electrician on staff, carrying commercial liability insurance and WSIB coverage. Our electricians are certified through Skilled Trades Ontario, and every upgrade is filed with the Electrical Safety Authority.
Our Process
We assess your existing panel and equipment load, plan the upgrade around your business hours where possible, and coordinate any required utility disconnect with minimal downtime.
Minimizing Downtime During the Swap
A full panel replacement typically means a period without power to the affected area, so we plan the sequencing to keep that window as short as realistically possible, often a matter of hours rather than a full day, and we tell you exactly when to expect it so you can plan around it rather than being caught off guard mid-shift. For properties that genuinely cannot tolerate any downtime, we can discuss a temporary generator connection to keep critical systems running through the swap, though this adds cost and is usually only worth it for specific high-stakes situations.
Protecting Your Business
An unpermitted commercial panel upgrade is a real liability exposure and a common finding at a fire or insurance inspection. Every job we complete comes with an ESA Certificate of Inspection your insurer and landlord can rely on.
Panel Brands and Recalls
Some older commercial panel brands have documented safety issues or recall history that insurers specifically flag during a policy review. If your panel matches one of these brands, we identify it during the assessment and explain what replacement actually involves, rather than letting it surface for the first time in an insurance letter.
Getting Started
Call us with your property type and current panel size. We will schedule a free, on-site assessment and give you a fixed quote before any work begins. We also flag any secondary issues we notice during the assessment, like undersized feeder cable or aging breakers elsewhere in the system, so you have the full picture before deciding scope.
Coordinating the Utility Disconnect
A panel replacement usually requires a brief service disconnect from the utility, which has its own scheduling lead time separate from our own crew. We coordinate that request early in the project so the disconnect window lines up with our install day instead of adding an unplanned delay.
Frequently Asked Questions
How do I know if my commercial panel needs upgrading?
Frequent trips, no room for new circuits, or an aging panel flagged during inspection are all signs. We assess this on site.
Can you upgrade a panel without shutting the business down?
Often yes, with planned timing and a brief coordinated disconnect; we discuss this during the assessment.
Do you work with landlords and property managers?
Yes, including direct billing and coordination on base building requirements.
Will you give me a price before starting?
Yes, a clear, fixed quote before any work begins.
Do you handle the ESA permit?
Yes, we file the notification and schedule the inspection as part of the job.
