Ontime Electric provides licensed electrical panel services across Markham — upgrades, replacements, repairs, relocations, and new installations. Markham spans heritage homes in Unionville and Markham Village and large newer subdivisions like Cornell, Berczy, Wismer, and Cathedraltown. Older village homes may still have 100 amp service or a fuse box, while larger and newer Markham homes may need more capacity for EV chargers, home offices, air conditioning, and finished basements. We handle both to the Ontario Electrical Safety Code, with the ESA Notification of Work and inspection included.
Electrical Panel Upgrades
Older electrical systems may struggle to handle today’s appliances, EV chargers, renovations, and increasing energy usage. Upgrading your panel improves reliability, enhances safety, and helps maintain compliance with current electrical and insurance requirements.
Benefits:
- Reduced Fire Risk – helps minimize overloaded circuits and electrical hazards.
- Improved Efficiency – supports more reliable power distribution throughout the property.
- Increased Capacity – accommodates modern appliances and future electrical upgrades.
- Improved Property Value – updated electrical systems are attractive to buyers.
100 amp to 200 amp Panel Upgrades
Many Markham homes benefit from upgrading to 200-amp service to support modern lifestyles and growing electrical demands. Older systems may not safely handle renovations, basement additions, or high-demand appliances. Because a service upgrade changes your connection to the grid, we coordinate the service and meter with Alectra Utilities (Markham’s local distributor) and arrange the ESA inspection, so the job is fully documented and compliant.
Electrical Panel Installation
New builds, additions, and major renovations often require a completely new panel installation. Our electricians install dependable, code-compliant systems designed for long-term safety and performance.
Electrical Panel Relocation
Panel relocation may be necessary during remodeling projects or layout changes. We relocate electrical panels safely while ensuring the installation remains compliant with Ontario electrical safety standards.
Electrical Panel Repair
Not every issue requires a complete replacement. In some situations, targeted repairs can restore safe operation and extend the lifespan of your electrical system.
Our Markham electricians diagnose panel problems efficiently and recommend practical, cost-effective solutions based on the condition of the equipment.
Electrical Panel Replacement
Older fuse boxes and aging breaker panels can become unreliable over time. Replacing outdated equipment improves electrical performance, enhances protection, and helps reduce the risk of overheating or power interruptions. This includes replacing aging panels and certain Federal Pioneer Stab-Lok components that may raise safety or insurance concerns, including when an insurer requests replacement before issuing or renewing coverage.
Fuses vs. Circuit Breakers:
- Fuses: Older technology that must be replaced after overloads.
- Circuit Breakers: Automatically shut off power during faults for improved safety and convenience.
Electrical Panel Maintenance
Routine maintenance helps keep your electrical system operating safely and efficiently. Our team inspects components, identifies potential concerns, and performs necessary repairs or adjustments before larger issues develop.
Preventive maintenance can improve reliability, extend equipment lifespan, and help avoid unexpected electrical problems.
Fuse Box to Breaker Panel Upgrade
Replacing an older fuse box with a modern breaker panel improves safety, convenience, and overall electrical performance. Modern breaker systems are better equipped to manage today’s electrical loads and provide stronger protection against overloads and short circuits.
Signs You May Need a Panel Upgrade
Whether you’re in a heritage Unionville home or a newer Markham subdivision, capacity is a common panel issue we’re called for. Your electrical system may need attention if you notice:
- Frequent breaker trips
- Flickering or dimming lights
- Buzzing sounds near the panel
- Burning smells or heat around breakers
- Limited capacity for renovations or EV chargers
- An older fuse box or outdated electrical service
- A Federal Pioneer / Stab-Lok panel (often flagged by insurers)
These warning signs may indicate that your electrical panel is no longer operating efficiently or safely. A professional inspection can determine whether repair, replacement, or an electrical service upgrade is the most appropriate solution.
