Commercial building owners and property managers across Toronto and the Greater Toronto Area (GTA) are entering a period of accelerated energy transition.
On February 24, 2026 Steve Hubbard from Lightenco joined Thomas Geekie of Toronto Hydro to speak to members of the Toronto Building Managers’ & Operators’ Association.
Steve shared that in 2026, three forces are converging that have a significant impact on building owners and property managers:
- Rising electricity costs in Ontario
- The federal phase-out of fluorescent lighting
- Growing electrification demands (EV charging, heat pumps, tenant sustainability expectations)
If you operate a commercial, condo, or institutional building in Toronto, the question is no longer whether upgrades are coming.
The question is whether your building has a defensible capital plan.
Toronto Lighting Retrofits: Still the Highest-Impact First Step
For most GTA commercial buildings, lighting remains the most practical and highest-ROI starting point.
High-runtime areas often operate 24/7 such as:
- Parking garages
- Stairwells
- Corridors
- Mechanical rooms
A properly engineered lighting retrofit can deliver:
- 50–80% energy reduction in continuous-use spaces
- Reduced maintenance costs
- Improved safety and ESA code compliance
- Higher tenant satisfaction
- Increased Net Operating Income (NOI)
However, retrofits must maintain illumination standards under Ontario Electrical Safety Authority (ESA) requirements. Poor fixture swaps that reduce light levels below code can create liability exposure.
For reference on lighting safety standards, see the Ontario Electrical Safety Authority:
Lighting is not simply a cost-saving measure — it is foundational building infrastructure.
Network Lighting Controls in GTA Buildings: Beyond Basic LED Conversion
Most Toronto lighting upgrades today go beyond fixture replacement.
Modern commercial lighting systems include:
- Embedded occupancy sensing
- Daylight harvesting
- Power tuning
- Colour tuning
- Integration into Building Automation Systems (BAS)
Because lighting exists throughout a building, it becomes a distributed sensor network. This enables:
- HVAC optimization
- Cleaning efficiency
- Energy data analytics
- Capital planning support
Organizations like BOMA Toronto continue to emphasize operational efficiency and sustainability in commercial real estate.
Lighting controls are often the gateway to broader electrification readiness.
Ontario Energy Incentives for GTA Commercial Buildings (2026 Update)
Several incentive programs materially change the economics of retrofits in Toronto and the GTA.
1. Energy Performance Program (Ontario)
Recent updates increased performance incentives to:
- $0.08 per kWh off-peak reduction
- $0.30 per kWh on-peak reduction
For large GTA commercial buildings with high peak exposure, this creates significant multi-year incentive value.
Details available via Save on Energy:
2. Biz Energy Saver Program
For qualifying Toronto and GTA buildings, this program offers:
- Instant discounts on turnkey projects
- Lighting and controls eligibility (non-LED conversions)
- Mechanical upgrades including VFDs
- In some cases, up to 100% cost coverage
Unlike traditional rebates, these are upfront capital reductions.
Many GTA buildings complete lighting upgrades and later discover they could have reduced capex significantly by structuring the project differently.
The Fluorescent Lighting Ban in Canada: Why Toronto Buildings Should Plan Now
As of January 1, Canada began phasing out fluorescent lighting products, starting with compact fluorescents and expanding to other lamp types.
Implications for GTA commercial buildings:
- Ballast availability is declining
- Replacement parts are increasing in cost
- Maintenance budgets will rise
- Product scarcity will worsen
Even ballast-compatible LED tubes are temporary solutions.
We’ve written in more detail about the Canadian fluorescent phase-out and what it means for Ontario building owners here.
Building owners who proactively transition to LED lighting while incentives remain strong will avoid reactive, high-cost maintenance cycles.

Commercial Solar Incentives in Toronto & Ontario (2026 Outlook)
Commercial solar adoption in Ontario is increasing, particularly in buildings with strong behind-the-meter load.
Under current retrofit frameworks:
- Incentives approximate $860 per kW
- Federal tax measures and accelerated CCA may further reduce net cost
- Effective cost reductions can exceed 50% in some scenarios
However, solar in Toronto works best when:
- Roof condition supports installation
- Utility capacity is confirmed
- Transformer capacity is sufficient
- Electrification planning is integrated
Solar should be evaluated as part of a building-wide energy strategy — not as a standalone product.
Electrification Planning in Toronto Buildings: The Infrastructure Reality
Electrification demand across the GTA is increasing due to:
- EV charging installations
- Heat pump adoption
- Tenant decarbonization expectations
While feeder capacity may exist at the grid level, many Toronto buildings encounter constraints at:
- Transformer sizing
- Electrical distribution panels
- Cooling infrastructure
Electrification planning requires coordination between building infrastructure and utility considerations.
Organizations such as Toronto Hydro and Hydro One continue to invest in grid modernization:
However, building-level constraints often determine feasibility timelines.
The Most Important Question for GTA Building Owners
Before proceeding with any retrofit, ask:
- What incentives apply to this building specifically?
- How does lighting sequencing affect electrification readiness?
- What infrastructure constraints exist?
- What is the defensible ROI?
- How do upgrades affect long-term NOI?
The most successful Toronto retrofit projects begin with structured diagnostics and engineering-grade planning.
In many cases, this takes the form of an ASHRAE Level 2 or 3 energy audit combined with decarbonization modeling and incentive mapping.
A Strategic Upgrade Path for Toronto & GTA Buildings
For commercial and condo building owners in the GTA, a disciplined sequence often looks like:
- Structured building performance diagnostic
- Incentive mapping before scope commitment
- Lighting and controls modernization
- Electrical capacity and electrification readiness assessment
- Solar feasibility review
- Phased implementation aligned with capital planning cycles
Buildings that approach upgrades as integrated capital planning exercises consistently reduce risk and improve financial outcomes.
Next Step for Toronto & GTA Building Owners
If you operate a commercial or condo building in Toronto or the GTA and are uncertain how lighting retrofits, Ontario energy incentives, electrification planning, and solar fit together, start with clarity.
Lightenco works with commercial and institutional buildings across Ottawa and the Greater Toronto Area to deliver:
- Engineering-grade energy audits
- Capital planning roadmaps
- Incentive strategy
- Turnkey implementation
Schedule a structured building performance diagnostic to understand:
- What programs your building qualifies for
- What sequencing makes financial sense
- How to future-proof your infrastructure
Because in 2026, competitive advantage in the GTA isn’t simply upgrading.
It’s upgrading with a defensible strategy.
