A federal bill that would rewrite large parts of Canada's Energy Efficiency Act is halfway through Parliament. According to LEGISinfo, Bill S-4 passed third reading in the Senate on June 2, 2026, after a committee reported it with amendments, and received first reading in the House of Commons on June 5. When we checked on October 23, 2026, it was awaiting second reading in the House. The Energy Efficiency Act is the law behind every federal efficiency standard for furnaces, heat pumps, air conditioners and water heaters.
What the bill would do
The short answer: wider scope, new enforcement tools, and a formal way to grant exemptions.
The bill's official summary, in its first-reading text, lists three aims:
- Exemptions. Let the Minister of Natural Resources grant exemptions from the Act and its regulations, to support innovation, competitiveness and economic growth.
- Enforcement. Strengthen administration and enforcement, including administrative monetary penalties, modernized fines and the power to order corrective measures.
- Scope. Broaden the Act to cover modern technologies and new market actors, address misleading representations and promote responsible energy use.
Key provisions in the first-reading text
From our reading of the bill as introduced on November 26, 2025:
- Products that control energy. Products or systems that affect or control energy consumption, not only those that use energy, could be prescribed under the Act.
- Broader standards. An "energy efficiency standard" could address factors such as durability, interoperability, energy demand, water conservation and system design.
- Dealers. The definition would include people who advertise or offer for sale or lease products obtained from manufacturers or importers. Dealers could not make false or misleading claims about energy efficiency.
- Digital labels. Labels could be physical or digital.
- Records. Dealers and a new category of "commercial entities" would report prescribed information and keep records for six years.
- Exemption orders. Short orders of up to six months, for example for harmonization, and three-year orders for testing innovations, extendable to six years.
- Penalties. Administrative monetary penalties of up to $5,000 for individuals and $25,000 for others, and higher court fines, with a due diligence defence.
- Corrective orders. The Minister could order a party to stop importing, selling, advertising or testing a product, with a short review process.
The Senate adopted committee amendments in May 2026. We have not compared the amended text line by line, so treat the details above as the bill as introduced.

What it means for contractors (analysis)
This section is our analysis, not part of the bill or LEGISinfo.
Efficiency claims in ads would carry more risk. The bill targets misleading representations about energy efficiency and extends "dealer" to those who advertise products. Contractors who quote efficiency ratings, savings or "meets federal standards" in ads and on websites should make sure each claim matches the manufacturer's published data. Accurate, dated claims were already good practice; under S-4 they may also be safer. Our HVAC websites and paid search work treats every efficiency number as a sourced claim.
Controls and systems could come under federal rules. Allowing products that "affect or control" energy use to be regulated opens the door to future standards for thermostats, controls or system-level performance. Nothing changes until regulations are written, but contractors who sell controls should watch NRCan's regulatory plans.
Penalties make supplier compliance matter. If a distributor sells a non-compliant unit, the consequences under a modernized enforcement regime could be larger. Ask suppliers how they track federal compliance for the products you install.
The regulations are where the detail lives. For the standards themselves, see our stories on Amendment 18 and SEER2 and the proposed Amendment 19.
What to watch next
The next step is second reading in the House of Commons, followed by committee study, where industry groups can again present views. If the House amends the bill, it returns to the Senate. We will update this story when the bill moves, with the date from LEGISinfo. All our coverage is in the newsroom.

Frequently asked questions
Is Bill S-4 law?
No. As of October 23, 2026, LEGISinfo showed the bill at second reading in the House of Commons, with its last activity on June 5, 2026. It becomes law only after passing the House and receiving Royal Assent.
Does Bill S-4 change efficiency standards for furnaces or heat pumps?
Not directly. It changes the law under which standards are made. Specific standards, such as those in Amendments 18 and 19, are set by regulations under the Act.
Would contractors be affected?
The bill's main duties fall on dealers, importers and those who ship or advertise regulated products. The first-reading text broadens 'dealer' to include people who advertise or offer for sale products obtained from manufacturers or importers. How that applies to a given contractor is a legal question, not something we can answer.
Did the Senate change the bill?
Yes. A Senate committee reported it with amendments on May 27, 2026, and the report was adopted on May 28. Our summary below is based on the first-reading text, so details may differ in the version now before the House.
