Commercial Building Electrical Thermography in the GTA

What Commercial Building Electrical Thermography Covers

Commercial building electrical thermography covers the base building distribution that tenants depend on: the main service and switchboard, splitters and distribution panels, floor and suite panels, and the equipment that keeps lifts, HVAC, parking and life safety systems running. We scan it energized, in normal service, without interrupting tenants.

• Service and main distribution: main switchboard, metering sections, splitters and feeder breakers in the main electrical room.
• Floor distribution: stacked electrical closets, step-down transformers, and the panels feeding each floor.
• Tenant and suite panels: where the lease and access allow, including retail units and restaurants with heavy cooking loads.
• Mechanical loads: rooftop unit disconnects, chiller and boiler starters, pump and fan motor controls, elevator machine room disconnects.
• Parking and exterior: garage lighting panels, ramp heating, gate controls, and electric vehicle charger panels.
• Standby systems: automatic transfer switches and the distribution they feed, when they can be seen carrying load.

Scanning technique is covered in depth under electrical thermography basics. What changes in a commercial building is access, tenants, and who is responsible for which panel.

Infrared Scans for Property Managers With Several Buildings

An infrared scan for property managers works as one program across the portfolio: the same equipment numbering, the same report layout and the same rating scale in every building, so you can compare sites and plan spending from one summary. A pile of one-off reports in different formats is hard to act on.

For portfolio clients we set up:

• A building register listing every electrical room and panel in scope at each address, which becomes the route for every future scan.
• A consistent equipment ID on every report, matched to your labels or to a numbering system we agree with your operations team.
• A portfolio summary ranking findings across all buildings, so the most urgent items rise to the top whichever property they are in.
• Per-building reports that site staff and building operators can use on their own.
• A calendar that spreads visits through the year, so scans fall at representative load and your team is not managing every building in the same month.

This structure is useful whether you manage office towers in downtown Toronto, industrial condos in Vaughan, or plazas and medical office buildings in Richmond Hill. Our property management page describes the rest of what we do for portfolio owners.

Scanning Occupied Buildings Without Disturbing Tenants

We scan occupied buildings during business hours because that is when the electrical load is real, and we do it quietly: no power interruption, no noise, and a crew that works around tenant schedules and building rules. Most tenants will not notice the visit beyond a notice in the lobby.

• Notices. We give you a short notice text for tenants, naming the date and explaining that power will stay on.
• Keys and escorts. Your building operator or security team provides access to electrical rooms and suites. Where suites cannot be entered, the panels are listed as not scanned.
• Load timing. Offices are scanned mid-morning to mid-afternoon on working days, restaurants during service, and retail when stores are trading. Cooling-dominated buildings are usually scheduled for summer, when mechanical loads peak.
• Safe access. Licensed electricians remove covers after a CSA Z462 risk assessment and close the room before leaving. Rooms are never left open or unattended.
• Building rules. We follow your contractor sign-in, insurance and orientation requirements and provide a WSIB clearance certificate before the visit.

Our office line is staffed seven days a week, mornings through evenings, which makes it easier to coordinate dates with building staff who work outside regular office hours.

Base Building and Tenant Panels: Who Owns Each Finding

Every finding in our commercial reports is tagged as base building or tenant equipment, based on the responsibility split your leases set out, so you know at once whether the repair is yours to fund or the tenant's to arrange. That single column saves a lot of back-and-forth.

The tags follow your instructions; we do not interpret leases. Where ownership is unclear, the finding is marked for your review. Tenant findings can be passed on with the relevant pages only, so tenants do not see the rest of the building report.

How Scans Differ for Offices, Plazas, Industrial Condos and Medical Buildings

The route and the timing change with the kind of building, because each type loads its electrical system differently and gives us different access. Planning around that is what keeps a scan useful instead of a tour of idle panels.

• Office towers. Stacked electrical closets and step-down transformers on each floor, heavy cooling loads in summer, and tenant server rooms that never switch off. Access is usually well organized through building operations.
• Retail plazas and strip malls. Each unit often has its own service or meter, with restaurants and grocery tenants carrying far more load than the original design expected. Unit access depends on tenant cooperation.
• Multi-tenant industrial buildings and condos. Small manufacturers, shops and warehouses share a service, and tenant machinery changes over time. A unit that turned into a machine shop can overload a panel sized for storage.
• Medical office buildings. Clinics, imaging suites and dental offices depend on steady power, so repairs are scheduled with extra care around patient hours. See our healthcare facilities page for that sector.

Mixed portfolios get a route per building type, all reported in the same format. The building register records which type each property is, so the next visit starts with the right plan and the right access arrangements already in place.

Planning a Year of Building Scans

Most commercial buildings are scanned once a year, with the main switchboard and other critical distribution scanned twice a year if equipment is older, heavily loaded or repeatedly flagged. Under the 2023 edition of NFPA 70B, the thermography cycle is a year for gear rated Condition 1 or 2 and half a year for Condition 3.

A yearly plan for a portfolio usually looks like this:

• Spring: buildings with heavy heating loads, before the season fully ends, and properties with insurance renewals in early summer.
• Summer: cooling-dominated office buildings and retail, when chillers and rooftop units load the system.
• Fall: re-scans of repaired items, and any building whose survey was moved for tenant reasons.
• Winter: buildings with electric heat, snow-melt or ramp heating systems, while those loads are running.

If an insurer has asked for a scan at a particular property, we can align the visit with the renewal date; the details of that are on our insurance infrared scan page. Since NFPA 70B has no legal force in Ontario unless a lease, contract or policy brings it in, CSA Z463 is the Canadian standard we use to frame the wider maintenance program, and each building scan follows the infrared inspection tasks of ANSI/NETA MTS (2023 edition).

Using Thermal Findings in Capital Planning and Reserve Studies

Thermal scan results help property managers and owners decide which electrical equipment to repair, which to watch, and which to budget for replacement, because they show actual condition rather than age alone. Several years of scans make that case far stronger than a single visit.

Repeated findings on the same switchboard, panels that run hot because tenant loads have grown, and transformers that run warm year after year are all signs that a capital project is coming. We summarize these patterns at portfolio level so asset managers can rank them alongside roofing, mechanical and elevator work. For condominium corporations, the same data can support the electrical section of a reserve fund discussion with your engineer.

Longer-term condition tracking, including testing results and equipment age, is covered under electrical asset management. Day-to-day upkeep of base building electrical systems is part of our commercial electrical maintenance service.

Ontario Electrical Rules Property Managers Should Know

Ontario reserves electrical work done for others to licensed electrical contractors, with limited exemptions, and work on an installation generally has to be reported to the Electrical Safety Authority (ESA) through a notification of work. A thermal scan itself is a condition survey, but the repairs it leads to fall under those rules.

• Check the licence. ESA advises building owners to always ask for the ECRA/ESA licence number. Ours is #7014042, and it can be verified on ESA's online contractor look-up.
• Notifications for repairs. When we repair a finding, we file the ESA notification so the work is on record.
• ESA Continuous Safety Services. ESA runs a program for property managers, manufacturers and health care providers with frequent electrical maintenance: a facility review, scheduled inspections, a dedicated inspector, and an online logbook instead of requesting an inspection for each job. Large portfolios may find it worth discussing with ESA.
• WSIB clearance. Owners who directly retain a contractor for construction work should obtain a WSIB clearance certificate, and keep the record.

We also keep a written record of every repair, matched to the finding in the original thermal report, so your files show the full chain from scan to fix.

Repairs and Follow-Up for Building Findings

After the report, our licensed electricians can repair the findings, usually after hours or on a weekend if an outage would affect tenants, and then re-scan the repaired points at the next normal-load opportunity. You approve the scope and timing first.

Typical building repairs include re-terminating loose feeder and branch connections, replacing heat-damaged breakers or fuse holders, rebalancing loads across panel phases, and upgrading a panel that tenant growth has outgrown. If a panel shows repeated or widespread problems, an electrical panel inspection with a closer physical check is the next step. Where main switchboard findings need a planned shutdown, we coordinate the outage notice, the utility where required, and the restart.
