The Cost of Power
There is no such thing as a Canadian electricity price. Power is set province by province, and the spread is enormous: the cheap-hydro provinces — Quebec at roughly C$0.05/kWh, British Columbia and Manitoba at C$0.06–0.08 — sit at one end, while Ontario (~C$0.10–0.15), the deregulated and volatile Alberta market (~C$0.10–0.12+), and the Maritimes (Nova Scotia, New Brunswick and PEI at C$0.15–0.19+) sit at the other. For a factory, data centre, or commercial estate, the province you operate in is the single biggest factor in what a kilowatt-hour costs — and how much there is to save by not wasting any.
Where power is cheap, the energy-savings lever is weak — in Quebec, BC and Manitoba the kilowatt-hour is simply too inexpensive to chase, and the case rests on capacity and equipment protection. But across Ontario, Alberta and the Maritimes, tariffs run two to four times higher, and the argument that “industrial power is cheap, efficiency doesn’t move the needle” does not hold: every percentage point of wasted current is charged at a real rate, and Ontario layers a power-factor-sensitive demand charge on top.
| Where / who pays | Typical all-in price | Notes |
|---|---|---|
| Quebec / Manitoba / BC (hydro) | ~C$0.05–0.08/kWh | Cheap, clean hydro — the savings lever is weak here |
| Ontario (commercial) | ~C$0.10–0.15/kWh | High tariff plus a power-factor demand charge — the strongest case in Canada |
| Alberta (deregulated) | ~C$0.10–0.12+/kWh, volatile | Pool prices swing widely — demand control is a hedge as well as a saving |
| Maritimes (NS / NB / PEI) | ~C$0.15–0.19+/kWh | The highest mainland tariffs — the tariff alone carries the case |
| Households (national, incl. taxes) | ~16 ¢/kWh (range ~8–24¢) | Mirrors the same provincial spread — cheap in Montreal, dear in Alberta and the Prairies |
Provincial and city tariffs are from the Hydro-Québec 2024 Comparison of Electricity Prices (which reports all-in city rates such as Montreal ~9¢, Toronto ~15¢, Halifax ~19¢ and Calgary ~23¢/kWh) and the Canada Energy Regulator; the household figure is the national residential average of about 16 ¢/kWh, within a Canada-wide range of roughly 8–24 ¢/kWh, from the same Hydro-Québec 2024 study. Figures are current as of 2024 and are revised regularly — verify against the Canada Energy Regulator and your provincial utility’s published rate schedule at the time of reading. All prices are in Canadian dollars (C$) and are unit rates that exclude site-specific demand and capacity charges. Last reviewed June 2026.
How You’re Billed
The headline cents-per-kWh is only part of the story. A demand-metered Canadian site pays for the energy itself, for the networks that deliver it, for provincial charges — and, critically for power quality, for the demand it places on the grid, measured in kW or kVA. In Ontario that demand charge is power-factor-sensitive, and in much of the country it moves directly when you correct power factor.
| Component | What it is | Cut by power quality? |
|---|---|---|
| Energy (commodity) | The kWh you consume, at the provincial or pool price | Indirectly — lower network losses |
| Delivery / network charges | Transmission and distribution of power over the grid | Partly |
| Provincial charges & riders | e.g. Ontario’s Global Adjustment, regulatory and other line items | Partly |
| Demand charge (kW or kVA) | A charge on the peak demand you place on the network — in Ontario, billed on the greater of metered kW or 90% of metered kVA | Yes — correcting power factor lowers the billed kVA |
| Peak-demand exposure (ON: Global Adjustment / ICI) | Large Ontario users can be charged on their share of the province’s top five peak hours | Yes — shaving peak demand reduces it |
So the answer to two questions Canadian operators often ask: yes, you are billed for demand — in kW or kVA — and in Ontario, yes, you are billed for poor power factor, because the demand charge is levied on the greater of kW or 90% of kVA, so a low power factor inflates the billed figure every month. Both fall as power factor rises toward unity, which is exactly what correction delivers.
Power Factor & Regulation
Canada has no single nationwide power-factor penalty — but it does not need one for the case to land, because the largest market sets the clearest rule. In Ontario, utilities such as Hydro One and Toronto Hydro bill demand on the greater of metered kW or 90% of metered kVA. The arithmetic is unforgiving: a site running at 0.80 power factor is billed on its full kVA rather than its lower kW, so it pays a measurable premium every month — a premium that simply disappears once power factor is corrected to 0.98+. On top of that, Ontario’s Global Adjustment and Industrial Conservation Initiative reward large users for shaving their share of the province’s top five peak hours, which demand control directly addresses.
On harmonics and supply quality, Canadian connections work to the Canadian Electrical Code and to harmonic distortion limits that consultants specify under IEEE 519 (alongside CSA standards). As variable-speed drives, rectifier loads, non-linear UPS and behind-the-meter solar multiply on Canadian sites, staying inside those limits increasingly requires active harmonic filtering — not just a one-off survey.
The kW-or-90%-kVA demand-billing rule is set per Ontario utility and published in their business-rate documentation (e.g. Hydro One and Toronto Hydro); Global Adjustment and the Industrial Conservation Initiative are administered by the IESO; harmonic limits are specified to IEEE 519 alongside CSA standards, and installations follow the Canadian Electrical Code and provincial wiring permits. Power-factor thresholds, demand-charge schedules and incentive terms vary by province and by utility and are updated periodically — confirm the charges and limits that apply to your connection with your local utility and provincial regulator.
Why Power Quality Matters Here
Three structural forces make power quality a Canadian boardroom issue, not just an engineering one. First, the tariff — but only in the right provinces: in Ontario, Alberta and the Maritimes the unit rate and demand charges are high enough that correction pays, while cheap-hydro Quebec, BC and Manitoba lead instead on the other two forces. Second, the generation mix: Canada runs on roughly 60% hydro, about 13% nuclear and around 7% wind and solar, and as that inverter-based share grows it raises harmonic distortion and voltage volatility at exactly the commercial and industrial sites we serve. Third, capacity: connection upgrades and interconnection waits are slow — Alberta alone has more than 10 GW of proposed data-centre projects in its queue — so freeing transformer and switchgear headroom on the connection you already have lets a growing or electrifying site add load without waiting for the grid.
What matters less in most of Canada is resilience. The grid is generally reliable — the most visible exception being weather-driven distribution outages in Quebec, where ice storms and remote feeders can produce long restoration times — so outside those exposed areas, Canadian operators are driven by cost, demand charges, capacity and compliance rather than by keeping the lights on.
The Solution
HarmoniQ installs a coordinated, solid-state system at the low-voltage switchboard — where Canadian sites carry their cost, where Ontario meters the kVA demand that drives the bill, and where the inverter-heavy grid injects distortion. We deploy three products as the site requires: the HarmoniQ Booster for real-time power factor correction, the HarmoniQ Filter (HPF) for harmonic mitigation, and HarmoniQ Alpha as the integrated platform tying correction, filtering and voltage optimisation together. No switched-capacitor steps, no contactors, and no resonance risk with the harmonics already on your system.
Real-time true power factor correction to 0.98+ across the whole network — removing the Ontario kVA-demand penalty (billed on the greater of kW or 90% of kVA), reducing apparent-power demand, and freeing transformer headroom so you can add load without a costly utility upgrade or a long interconnection wait.
Active harmonic filtering that holds distortion below the limits consultants specify to IEEE 519 — the component that matters most in Canada’s commercial, cold-chain and data-centre sites, where VFD-driven chillers, rectifier loads, non-linear UPS and on-site solar all push harmonic levels up.
Unifies correction, filtering and voltage optimisation across multiple boards or sites — stabilising voltage for sensitive loads in hospitals, data halls and process plants, and giving the visibility to prove power factor, harmonics and kVA demand at the meter, continuously.
Why not just install capacitor banks? + Read more− Close
Switched-capacitor banks correct power factor in fixed steps at the incoming feed — enough, in theory, to lift you over a kVA-demand threshold at the meter. But they respond in steps and seconds, so they lag fast-changing loads; they sit only at the boundary, so reactive current still flows through your internal network; and on a system carrying harmonics — as nearly every modern Canadian site does, with its drives, rectifiers and inverters — a capacitor bank can form a resonant circuit with the supply, amplifying those harmonics.
HarmoniQ is solid-state and dynamic: it corrects continuously rather than in steps, works across the network rather than at one point, and carries no resonance risk. Paired with active filtering, it is power factor correction and harmonic mitigation designed for a plant full of drives and inverters, not the switchgear of forty years ago.
What It’s Worth
| Lever | What changes | Effect on the bill |
|---|---|---|
| Power factor → 0.98+ | Billed kVA demand falls toward billed kW | Ontario kVA-demand charge cut; demand fees lowered |
| Energy & loss reduction | ~2–3% of losses recovered on a high-tariff bill | Lower energy spend, cooler transformers & cables |
| Capacity release | PF 0.80 → 0.98 frees ~15–20% of transformer / switchgear headroom | Defer a utility upgrade or interconnection wait; add load now |
| Equipment-life extension | Less harmonic and thermal stress on motors, drives and UPS | Longer asset life, fewer nuisance trips |
| Indicative annual saving | A material recurring sum on a high-tariff site of this size — plus the capacity released | |
Every site’s loads, province, tariff and power-factor profile are different, and the figures above are illustrative of the mechanism — not a quote. The same building is a marginal prospect on cheap Quebec hydro and a strong one on an Ontario or Maritimes tariff, so the first thing our engineers establish is whether your province carries the case. They will then model the exact power factor improvement, kVA-demand charge avoided, losses recovered and capacity released for your specific connection — and, in Ontario, whether Save on Energy incentives can co-fund it — get in touch for a site assessment, or see the method on our power factor correction and demand-charge pages.
