Finding sustainable building materials in Canada is easier than it was five years ago. The selection has grown. But the real headache hasn’t changed: most of these products are scattered across specialty stores, niche websites and regional distributors that don’t always show up when you search online. If you’ve tried to source low-VOC flooring or FSC-certified wood outside of a LEED-focused commercial project, you already know how fragmented the supply chain still is.

This list is practical. Every retailer here carries eco-friendly products you can order and receive in a reasonable timeframe, whether you’re a homeowner tackling a renovation or a contractor building to GREENGUARD or FloorScore standards. Some are specialists. Some are larger retailers with green product lines you might not know about. All of them ship within Canada or have physical locations worth the drive.

Where to Buy Green Building Materials in Canada

---

1. Eco-Building Resources

Aurora, Ontario (ships Canada-wide)

If you need something specific for a high-performance wall assembly or a Passive House build, Eco-Building Resources is where a lot of Canadian builders end up.

The retail location on Wellington Street in Aurora doubles as a showroom where you can see and feel these materials before committing. Online ordering is available too.

What they sell – Hemp batt insulation, zero-VOC finishes, non-toxic sealants, porous paving, AFM Safecoat, SIGA air-sealing tapes.

Best for – Anyone chasing LEED credits or Passive House certification, the product range maps directly to those material requirements. Worth bookmarking even if you don’t need it today.

Limitations – Focused inventory, not a big-box catalogue.

2. L’Entrepôt de la Réno

Québec, Québec (ships province-wide)

Not every green renovation runs on a Passive House budget. Most homeowners want to make better material choices without paying a premium over conventional products, and that’s the space where Entrepôt de la Réno operates.

Pricing sits below what you’d pay at a Rona or Home Depot for comparable specs, because the operation is lean: direct-to-consumer online sales with delivery across Quebec, no sprawling retail footprint eating into margins.

What they sell – SPC vinyl planks with phthalate-free rigid core construction, engineered hardwood from managed forestry sources, ceramics and porcelain tiles produced without heavy metal glazes.

Best for – If you’re renovating a kitchen or bathroom in Quebec and your budget is real-world rather than aspirational, this is one of the few places where sustainability and cost aren’t fighting each other.

Limitations – Limited range of green building materials.

3. Habitat for Humanity ReStores

100+ locations across Canada (some locations offer delivery)

The greenest building material is one that already exists. ReStores accept donated and surplus building supplies and resell them at steep discounts: doors, windows, lumber, hardware, lighting, sometimes full kitchen cabinet sets.

Inventory varies wildly by location and by week, so patience is required. But the environmental math is simple. Materials stay out of landfill and go back into use. Proceeds fund affordable housing. You get product at a fraction of retail. For accent materials, fixtures or replacing a few components in a renovation, there’s no lower-impact option available anywhere in the country.

What they sell – Used cabinetry, fixtures, appliances, furniture, doors and windows and surplus building materials like lumber and tiles.

Best for – If you’re fine with used products or if you’re looking for smaller amounts of building materials.

Limitations – Product range is constantly changing depending on what new inventory comes in and what gets sold – you have to keep checking in order to find what you want.

4. RONA

375+ locations across Canada (ships Canada-wide)

RONA doesn’t market itself as a green retailer, and that’s precisely why it belongs on this list. A lot of people overlook it. But the ECO program flags items with recognized environmental certifications, and if you filter for it, the selection is bigger than you’d expect. GREENGUARD Gold-certified flooring. FloorScore-rated vinyl. FSC-certified lumber. Low-VOC paints and stains from Benjamin Moore Natura and Dulux Diamond Clean.

With 375-plus locations, you can inspect materials in person before buying. That matters for flooring especially, where texture and colour variation aren’t always obvious from a product photo on a screen.

Look for the “Well Made Here” label on Canadian-manufactured goods. Buying a product made in Ontario for a project in Ontario cuts transportation emissions without you having to do any extra research. The CaGBC factors regional sourcing into LEED credits for exactly this reason.

What they sell – RONA’s ECO program spans thousands of products identified with third-party environmental certifications, though the company does not publish a current total.

Best for – If you want the big-box shopping experience where you’ll be able to find a bunch of what you need all in one place.

Limitations – Not all products offered online are available in store and vice versa.

5. BMR Group

Quebec and Eastern Canada (ships Canada-wide)

BMR runs 275-plus stores across Quebec, Ontario and the Maritimes, and the product mix tilts towards the professional contractor market. Relevant for green building because the insulation, lumber and structural product lines already include options that meet or exceed current energy code requirements.

The cooperative structure (owned by Sollio Groupe Coopératif) means affiliated dealers carry region-specific products suited to local climate conditions. For a renovation in the Maritimes or rural Quebec where shipping specialty green materials from a niche online retailer isn’t realistic, BMR’s in-store inventory usually has something that works. Not the most extensive range of green building materials on this list, but when you need mineral wool batts and you need them this week, they have what you need and can get it delivered quickly.

What they sell – Wood fibre insulation, wood fibre siding, zero-VOC paint

Best for – Professional contractors and DIYers looking for a rather large range of products under one roof

Limitations – They have an extensive range of products, yet their range of green building products is comparatively minimal, so it’ll take some searching to find what you want.

6. HempWorks Canada

Kelowna, British Columbia (ships Canada-wide)

Hempcrete keeps showing up in green building conversations. Actually buying the raw materials in Canada? That’s been the hard part. HempWorks is one of the few domestic suppliers offering construction-grade hemp hurd, lime binders, hemp batt insulation and hemp flooring. You can also rent the mixing and forming equipment needed for hempcrete wall construction, which removes one of the barriers for builders who want to try it on an actual job.

The material itself is carbon-negative during its growth cycle. Excellent thermal mass, good moisture regulation, solid acoustic insulation. The CaGBC has started paying closer attention to bio-based materials like hemp in its rating systems. Shipping bulk hurd orders from B.C. can get expensive if you’re on the other side of the country, but HempWorks also offers project consulting for builders who’ve never worked with hempcrete before. Given how few tradespeople have hands-on experience with it, that consulting piece matters more than the product catalogue.

What they sell – Hempcrete, hemp batts, HempWood.

Best for – Anyone looking to build with hemp.

Limitations – Their products are limited to hemp.

7. Green Building Supply

Iowa, U.S (ships to Canada)

U.S.-based but with established shipping to Canadian addresses. Green Building Supply is one of the oldest dedicated non-toxic building material retailers in North America. The entire catalogue is curated around health and sustainability. Products get tested in-house before they’re listed, which is unusual in this space.

Cross-border shipping adds cost and lead time. That’s the tradeoff. But for certain non-toxic products with limited domestic availability, such as Marmoleum click tiles and AFM Safecoat, Green Building Supply is often a go-to source for Canadian buyers. The customer service team walks DIY installers through unfamiliar materials, which helps when you’re laying natural linoleum for the first time and the install process is nothing like vinyl.

What they sell – Forbo Marmoleum natural linoleum, zero-VOC bamboo flooring, recycled countertops, wool carpet, a deep inventory of non-toxic paints, sealants and adhesives.

Best for – if you’re looking for a wide range of flooring, finishes and kitchens.

Limitations – A focused lineup of products, not a full range of different materials available.

Before You Order Anything

---

A “green” label on a product page means very little without a credible third-party certification behind it. In Canada, the ones worth checking for include FSC or PEFC for responsibly sourced wood, GREENGUARD Gold and FloorScore for indoor air quality and emissions and ENERGY STAR for mechanical equipment. For more advanced projects, Environmental Product Declarations (EPDs), Declare labels and Cradle to Cradle certification offer deeper transparency on material health and lifecycle impact. If a retailer can’t point you to a valid certification listing or documentation, it’s a red flag.

Also think about where the product was made. A material manufactured in Ontario and sold in Ontario has a smaller carbon footprint from transportation alone than the same product shipped across the Pacific, even if the overseas version carries a better eco-label. When two products score similarly on emissions and toxicity, distance to your job site is the tie-breaker.

No single supplier on this list will cover every material on your project. You’ll piece it together from multiple sources, each one filling a different gap. That’s the reality of green building supply in Canada right now. But the options are there, and they’re easier to find than they were even two or three years ago.
