Quebec's electricity regulator has set Hydro-Québec's rates for a full three-year cycle. In a press release dated March 16, 2026, the Régie de l'énergie announced decision D-2026-033 and estimated the increase for Hydro-Québec's customers as a whole at 3.2% on average from April 1, 2026. The decision covers 2026, 2027 and 2028 together, as the province's new regulatory framework for energy resources provides.
What the Régie decided
The short answer: homes get 3.0% in 2026 and 2027 and 2.6% in 2028; businesses get 3.6% a year.
| Customer category | April 1, 2026 | April 1, 2027 | April 1, 2028 |
|---|---|---|---|
| Domestic (residential) | 3.0% | 3.0% | 2.6% |
| General and large-power industrial (rate L) | 3.6% | 3.6% | 3.6% |
The decision followed a public hearing held January 8 to 16 and January 20 and 21, 2026, with several groups representing consumers' economic, social and environmental interests. The Régie said the residential increases respect government decree 1239-2025, which capped certain domestic rate increases at 3.0% for the rate years beginning in April 2026, 2027 and 2028.
Hydro-Québec had announced its request on July 31, 2025, proposing 3% a year for residential customers and 4.8% a year for commercial and industrial customers.
How the residential increase is shaped
The short answer: the Régie loaded more of the increase onto higher consumption and froze the fixed access charge.
Two design choices matter for heating:
- Second energy tier. For residential customers, the Régie applied an increase twice as large to the price of the second tier of energy as to the first tier. Electrically heated homes in winter move into that second tier.
- Access charge frozen. The system access charge stays at its April 1, 2025 level.
The Régie said that combining the frozen access charge with a lower increase on the first tier helps protect small consumers and, with them, low-income households.
Estimated monthly impact
The short answer: a few dollars a month for most electrically heated homes, slightly less than Hydro-Québec had projected.
| Electrically heated home | Hydro-Québec's projection | Régie estimate |
|---|---|---|
| 5½ apartment, 68 m² | $2.40/month | $2.30/month |
| Small house, 111 m² | $4.90/month | $4.70/month |
| Medium house, 158 m² | $5.70/month | $5.46/month |
| Large house, 207 m² | $8.40/month | $8.05/month |

Analysis: what this means for heating contractors
This section is HeatingNews.ca analysis, not part of the Régie decision.
Quebec is the most electric heating market in the country: Statistics Canada's household survey shows electricity as the primary heating energy for 70% of Quebec households in 2023. With residential increases now known for three years, the rate story in Quebec is about predictability rather than shocks.
That changes how a heating contractor should talk about savings:
- Lead with the second tier. Because the larger increase lands on the higher-consumption tier, efficiency gains in winter, such as replacing baseboards with a cold-climate heat pump, are worth slightly more each year than a flat average suggests. Keep the claim modest and show the arithmetic.
- Pair rates with programs. Hydro-Québec's LogisVert grants and the federal heat pump rebate announced on October 8, 2026 are the stronger buying triggers; our Quebec page lists what was open when we checked.
- Publish in French first. Quebec's language rules require French on commercial websites aimed at Quebec customers. A rate explainer that exists only in English will miss most of the market. Our rate-change explainer pages can be planned bilingually from the start.
Key terms in the decision
The short answer: a few French regulatory terms appear in every Quebec rate story, and they are worth knowing.
- Tarifs domestiques are the residential and farm rates, including rate D for most homes.
- 1re et 2e tranche d'énergie are the two consumption tiers. Daily use up to a set threshold is billed at the lower first-tier price; anything above it, typical of electrically heated homes in January, is billed at the second-tier price.
- Frais d'accès au réseau is the fixed access charge on every bill, frozen in this decision.
- Décret is a government order. Decree 1239-2025 is the instrument that capped the domestic increase at 3.0%.
Knowing these terms helps when a homeowner forwards a French-language news story and asks what it means for their heating costs. It also helps contractors write accurate French content rather than translating English rate stories word for word.
What to watch next
Rates for April 2027 and April 2028 are already set by this decision, subject to any further regulatory steps. For a contrast with oil-heated regions, read our report on September's 57.8% rise in fuel oil prices, or browse the newsroom.
Frequently asked questions
How much did Hydro-Québec residential rates rise in 2026?
Residential (domestic) rates rose 3.0% from April 1, 2026, according to the Régie de l'énergie's decision D-2026-033. The Régie set the same 3.0% for April 2027 and 2.6% for April 2028.
What does that mean for a typical electrically heated home?
The Régie estimated monthly increases of $2.30 for a 68 m² apartment, $4.70 for a 111 m² small house, $5.46 for a 158 m² medium house and $8.05 for a 207 m² large house, all electrically heated.
Why is residential capped at 3%?
The Régie said the domestic increases respect government decree 1239-2025, which set 3.0% as the maximum increase for certain domestic distribution rates for the rate years starting April 1 in 2026, 2027 and 2028.
Do business customers pay more?
Yes. The Régie set 3.6% a year for general rates and large-power industrial customers on rate L, for each year of the cycle.
