How to Spot Greenwashing in Canadian Fashion Brands

What to take away

• The Competition Bureau treats an environmental claim as misleading if it cannot be backed by adequate testing, and it can seek penalties under the Competition Act.
• Provincial consumer protection law in Ontario, Quebec and British Columbia adds its own route for a misled buyer, separate from the federal file.
• Canadian labelling rules under the Textile Labelling Act and its regulations require fibre content by generic name, so a vague "eco blend" is already a problem.
• The failure that hurts most is quiet: a compostable or bio-based claim that looks fine on the tag and only collapses after a season of wear and washing.

The costly one

Situation: A Canadian brand sells a jacket as "100% compostable," and the claim appears on the hangtag and product page.

Consequence: It sits unchallenged for a full season, because nothing about a new jacket looks wrong in a store. The buyer finds out only at end of life, when their city's municipal program refuses it.

Prevention: Before the purchase order, not after the first shipment, ask the supplier for the test report behind the claim.

That mistake is worth warning about: it stays invisible for months or years. Compostability depends on facility conditions, and a home bin differs from an industrial site.

ASTM D6400 is written for industrial composting, so a brand that cites it for backyard bins overreaches. Canadian cities vary in what they accept, and most curbside organics programs exclude textiles outright.

The ones that look fine at first

A fiber content line reads "plant-based blend" instead of naming the fiber. The Textile Labelling Act requires dealers to label textile fiber products with each fiber's generic name and percentage by mass.

"Plant-based" is not a generic name, and this looks harmless because the fabric feels good and the story is appealing. It survives until a competitor or a consumer files a complaint.

A recycled content figure with no scope attached. "Made with 50% recycled materials" can mean the shell fabric, the lining, or the zipper pull, and the number on the page rarely says which. Ask for the mass balance or the traceability certificate that ties the percentage to a specific component.

A certification logo used outside its scope. A mill certificate for one fabric does not cover the finished garment, and a brand that borrows the logo for a whole collection is making a claim it cannot defend. The checks that matter most for biofabricated materials are a useful filter here, because they force the question of what exactly was certified.

The ones that only show up later

Pilling, fading and seam failure after ten washes turn a durability claim into a liability. A brand that markets a tee as long-lasting, then sees returns climb in month four, has a claim problem and a product problem at once. Prevention: wash-test a production sample before the full run, not a lab swatch.

Microfibre shedding is the second slow one. A bio-based synthetic can still shed, and the shed particles do not appear on any label. The microplastics background explains why a fibre that biodegrades in theory may persist in a river for years. Prevention: ask for shedding data from a wash test, and treat a missing test as a missing claim.

A "PFC-free" finish that quietly reverts to a fluorinated chemistry at the next production run. The PFAS overview sets out why these substances are regulated and why substitutions get reversed when water repellency drops. Prevention: require the finish chemistry in writing on every purchase order, not once at the start of the relationship.

Claim on the tag	What it hides	What to ask for
100% compostable	Which facility and which standard	Test report naming the standard and the facility type
Plant-based blend	Fibre names and percentages	Full fibre content by generic name
50% recycled	Which component	Traceability document tied to that component
PFC-free	The replacement chemistry	Written finish specification per order

What they have in common

Every failure starts with a claim easier to write than to prove. The brand drafts the marketing line first, then hunts for evidence. The gap between the two is where the risk sits.

Federal enforcement under the Competition Act and provincial consumer protection statutes both reach a false or misleading representation, intended or not.

A short internal rule fixes most of it. No environmental claim goes on a tag or a page until the supporting document is on file, dated, and tied to a specific product. The pre-purchase checklist for natural fibers works the same way for fibre claims, and it takes an afternoon to apply across a small range.

A claim you cannot produce a document for is not a claim. It is a liability with a print run.

Two more habits help. Keep the evidence file with the purchase order, so a staff change does not lose it. And review every claim once a year, because a supplier can change a finish or a fibre blend without telling the brand that prints the tag.

Common questions

Does Canada have a greenwashing rule aimed at fashion? No single fashion rule exists. The Competition Bureau applies the misleading representation provisions of the Competition Act, and provincial consumer protection statutes apply alongside it.

Is a certification enough on its own? Only if the certificate names the finished product and the site that made it. A mill-level certificate for one fabric does not cover a garment made from several materials.

How is this different from the U.S. approach? The FTC publishes Green Guides that shape its enforcement, while Canada relies on the Competition Bureau's environmental claims guidance and case-by-case action. The practical effect is similar: unsupported claims draw complaints.

What should a small brand do first? Pick the three claims that appear most often on tags and pages, and gather the document behind each one. Fix those before adding any new claim.
