Landfill Methane Regulations · SOR/2025-279

Turn landfill methane compliance into a revenue stream

Canada's federal landfill methane controls begin in 2028. Flaring meets the rules but earns nothing. McAlpha's modular CMR platform converts your recovered landfill gas into saleable low-carbon fuels.

What the regulations require

Canada's Landfill Methane Regulations in plain language

Made under the Canadian Environmental Protection Act, 1999 and registered on December 12, 2025, the Regulations set performance-based limits for landfills that receive municipal solid waste. The Government of Canada expects them to cut landfill methane by about 50% below 2019 levels by 2035.

01 · WHO

Which landfills are covered

Landfills that received municipal solid waste after January 1, 2010 and hold more than 450,000 tonnes of it, or that take in more than 20,000 tonnes a year (from 2025) and hold more than 200,000 tonnes.

02 · ASSESS

Annual methane assessment

By June 1 each year, owners calculate the previous year's methane generation with the federal modelling tool and report it, with site, waste and gas-system details.

03 · TRIGGER

Control thresholds

Methane controls apply at 1,000 tonnes of methane a year or more (from 2028 or 2029), and at 664 to 1,000 tonnes a year for open landfills (from 2035).

04 · CONTROL

No venting; destroy or use

Venting is prohibited. All recovered landfill gas must go to a flare, an energy recovery device, a treatment system that processes it for sale or use, or another device with at least 98% methane destruction efficiency.

05 · MONITOR

Wells, leaks and surface limits

Monthly recovery-well monitoring; leak checks three times a year (leaks at 500 ppmv or more); surface methane below 500 ppmv and zone averages below 25 ppmv, checked three times a year.

06 · REPORT

Records and annual report

Gas flow measured at least every 15 minutes and methane concentration at least monthly for each destruction device, with records kept and an annual report filed by June 1.

Your options

Flare it, burn it for power, or turn it into product

Every compliant pathway destroys or uses the methane. They differ in what you get back, especially as federal offset credits for regulated landfills wind down.

Pathway eligibility is set by section 8 of SOR/2025-279. Each installation should be confirmed with the regulator and site engineers.

The McAlpha CMR solution

How CMR turns landfill gas into low-carbon fuel

The Catalytic Membrane Reactor (CMR) platform combines catalysis and separation in one modular unit. It uses both the methane and the CO₂ in landfill gas.

Condition the gas

Removes hydrogen sulphide, siloxanes and moisture to protect the catalysts.

Make syngas

CMR-1 combines partial oxidation with dry reforming, so methane and CO₂ both become hydrogen and carbon monoxide.

Build liquid fuel

CMR-2 uses Fischer-Tropsch catalysis to turn syngas into C5+ paraffinic liquid hydrocarbons.

Separate and close the loop

Liquids, water and light gas are separated. Tail gas is recycled, used as fuel or sent to a flare or thermal oxidizer.

One platform, several product routes

The landfill pilot focuses on C5+ liquids. The same platform can be configured for other products to suit local markets.

Why landfill owners talk to us

Compliance first, value second, and both from the same gas

Your gas collection system, monitoring and reporting still do the compliance work. CMR adds a way to earn from the gas you are now required to recover.

Revenue after offsets end

Regulated landfills lose access to new federal landfill-gas offset credits, most from 2029. Product sales help recover the cost of gas collection.

Built for mid-size and remote sites

Skid-mounted modules sit near the gas source and scale by adding units. You don't need a grid connection or gas pipeline.

Measured, reportable performance

Metered feed, product, tail gas and carbon balance support the flow and concentration records the Regulations require.

Uses methane and CO₂

Dry reforming converts both main components of landfill gas. That improves carbon efficiency compared with routes that vent the CO₂.

Integrity and monitoring support

Our pipeline leak detection, methane emission monitoring and data management teams can support your monitoring program.

Flexible ownership

Equipment sale, build-own-operate, joint venture, service or licensing, matched to your capital plan.

FAQ

Landfill methane regulations: common questions

When do Canada's Landfill Methane Regulations take effect?

Methane control requirements begin on January 1, 2028 for portions of landfills generating 1,000 tonnes or more of methane a year that already have an active landfill gas recovery system. Other portions of those landfills follow from January 1, 2029 or later, and open landfills generating 664 to 1,000 tonnes a year from January 1, 2035 or later. The annual methane generation assessment is due by June 1 each year.

Which landfills are covered?

Landfills that received municipal solid waste after January 1, 2010 and hold more than 450,000 tonnes of it, and landfills that take in more than 20,000 tonnes of municipal solid waste in 2025 or any later year and hold more than 200,000 tonnes. Landfills that only ever received hazardous, inert, forest products or construction and demolition waste are excluded.

Can we use the gas instead of flaring it?

Yes. Section 8 allows recovered landfill gas to go to a flare, an energy recovery device, a treatment system that processes it for sale or use, or any other device with at least 98% methane destruction efficiency. A treatment system must send methane-containing process emissions and any unsold gas to a flare or thermal oxidizer.

What happens to our landfill gas offset credits?

Once a landfill is regulated, landfill methane recovery and destruction no longer qualifies for federal offset credits. The Government of Canada expects most regulated landfills to become ineligible from January 1, 2029 and the rest from January 1, 2035, so product revenue matters more.

How many landfills will be affected?

The Government's analysis estimates 147 landfills will incur compliance costs: about 85 starting in 2028, 37 in 2029 and 25 in 2035. It puts the total present-value cost at about $808 million from 2026 to 2040, for about 100 Mt CO₂e of reductions.

What does CMR produce from landfill gas?

The landfill demonstration targets C5+ synthetic liquid hydrocarbons. The platform can also be configured for renewable natural gas, hydrogen or methanol, depending on site economics.

What information do you need to screen our site?

Your latest methane generation estimate, landfill gas composition (methane, CO₂, oxygen, H₂S and siloxanes), recovered gas flow, current gas handling, and site layout and utilities.
