For Canadian procurement teams, paper bag rules Canada means the paperwork and specs you must require from your supplier: an FSC chain-of-custody code if you claim forest certification, a Letter of Guarantee for any food-contact use, and documented substantiation for any environmental claim on the bag or in your marketing. A domestic manufacturer makes these checks faster to verify and easier to keep on file.
TL;DR:
- Suppliers must provide third-party test reports, specific figures, and methodology details for environmental claims to meet new Canadian greenwashing regulations.
- Verifying FSC claims requires confirming supplier CoC codes, checking FSC registration, and examining relevant sales documentation for traceability.
- Food-contact paper bags need a Letter of Guarantee and technical data sheets, with records stored in your Preventive Control Plan for compliance.
- Clear specifications, prototypes, and approval documentation before mass production prevent costly rework and disputes later.
- Domestic manufacturing reduces lead times, simplifies documentation retrieval, and speeds up revisions compared to overseas sourcing.

What compliance and substantiation buyers must request
Since June 20, 2024, amendments to the Competition Act’s new greenwashing provisions have required businesses to hold adequate and proper substantiation for environmental claims, with the burden of proof resting on the party making the claim, not on a regulator to disprove it. That shifts real risk onto procurement and marketing teams who put words like “recyclable” or “sustainable” on a bag without backup.
The Competition Bureau’s guidance on environmental claims says acceptable substantiation generally relies on internationally recognized methodologies, and third-party verification is often expected under those methodologies. For a recycled-content claim, that means mill or run data showing the actual fiber source, not a general assurance from a sales rep. Our breakdown of recycled content claim documentation covers what that paperwork should include.
Build these into your RFQ language:
- Require the supplier to name the methodology or standard behind any environmental claim before you approve artwork.
- Ask for third-party test reports or certificates for claims tied to recyclability, compostability, or recycled content.
- Specify exact figures (“30% post-consumer recycled fiber”) instead of vague terms like “eco-friendly” or “green.”
- Add a contract clause requiring the supplier to retain substantiation records and produce them on request during an audit.
Pro Tip: Keep a claim file for every print run, matching the exact wording on the bag to the document that backs it up.
FSC and chain-of-custody: verifying forest-based paper claims
A supplier holding FSC chain-of-custody certification is not the same as a finished bag carrying an FSC label. The FSC-STD-40-004 Chain of Custody standard requires that organizations include supplier certification details, maintain traceability through the supply chain, and put FSC CoC codes on sales documentation for any product sold under an FSC claim.
Before you approve an FSC claim on your bag:
- Request the supplier’s FSC CoC code in writing as part of the RFQ response.
- Verify the certificate on the FSC database, checking status, scope, and the relevant product group.
- Confirm the sales and delivery documents list the CoC code and the specific claim type (100%, Mix, or Recycled).
- Ask for supplementary traceability records when the claim will appear in external marketing, not just on the bag itself.
Our FSC-certified packaging guide for buyers walks through this verification in more detail.
Food-contact paper bags: safety documentation to collect
For takeout and delivery bags that touch food directly, responsibility for safety sits with the business under the Food and Drugs Act and the Safe Food for Canadians Act, both of which require packaging materials to be safe and suitable for their intended use. CFIA guidance on packaging materials confirms the agency no longer maintains a pre-approval list, so buyers now carry the documentation burden directly.
What to request from your supplier:
- A Letter of Guarantee (LOG) confirming the materials are safe for food contact.
- Any existing Letter of No Objection (LONO) or Letter of Acceptance tied to the specific inks, coatings, or adhesives used.
- Technical data sheets on inks and adhesives, particularly when printing extends near the food-contact surface.
Health Canada’s guidance on packaging materials notes that voluntary assessments are available when a supplier lacks existing documentation, and that these records belong in your Preventive Control Plan, not just in an email thread.
Pro Tip: File the LOG with the specific SKU and print run it covers; a generic LOG from a different product won’t satisfy a CFIA inspector.
Specification checklist for custom shopping bags
A clear spec sheet prevents disputes and rework later. Copy these fields into your RFQ:
- Material and weight: specify paper GSM appropriate to load (typically heavier stock for foodservice than retail boutique bags) and state any recycled-content percentage you require.
- Handles: specify handle type (twisted paper, flat paper, rope) and the load weight the handle must hold without failure.
- Printing: specify flexo printing with Pantone color matching, confirm water-based inks, and request die-line files with bleed and safety margins before plates are made.
- Pre-press deliverables: require a digital proof and a physical prototype before production, not after.
- Finishes: avoid coatings or laminates that compromise recyclability or food-contact safety, and keep claim language tied to the exact finish used.
Our supplier checklist for Canadian paper bag buyers expands on several of these fields if you’re building your first formal RFQ template.
Quality assurance before mass production
Rejected runs are expensive and avoidable with a structured proofing sequence. Follow this order before committing to full production:
- Approve the die-line, confirming dimensions, gussets, and fold lines.
- Review a digital proof for color accuracy and copy placement.
- Inspect a physical prototype for handle attachment strength, gusset and fold quality, and tear resistance.
- Run a short pre-production sample and inspect it against the approved proof.
- Request a final inspection report before the full order ships.
Ask your supplier for incoming material check records, press QC reports, and holdback samples from the actual run, not generic samples from a previous job. Document every approval in writing, including who signed off and when, so a change later in the process has a clear paper trail.
Pro Tip: Keep holdback samples from every production run for at least a year; they’re the fastest way to resolve a dispute over color or material drift.
Lead times, minimums, and domestic manufacturing advantages
Realistic timelines depend on artwork approval speed, plate-making, press scheduling, and finishing steps like handle attachment. Custom colors, specialty inks, or uncommon handle styles tend to push both minimums and lead times higher than a stock bag with standard printing.
Sourcing domestically changes the logistics picture:
- Freight stays within Canada, reducing the customs delays and border paperwork that come with overseas shipments.
- Warehousing and just-in-time stocking become realistic options instead of carrying months of inventory.
- Document retrieval for LOGs, CoC codes, and QA reports is faster when your supplier and your team work in the same time zone and regulatory system.
- Revisions to artwork or specs move faster when plates and dies are made close to home.
Buyers managing cross-border freight alongside domestic orders may also find guidance on compliance and logistics planning useful when comparing supply chain tradeoffs.
What procurement teams consistently get wrong
Most procurement teams treat paper bag sourcing as a one-time spec exercise: pick a material, approve a proof, place the order. The documentation problem shows up later, often during an audit or a customer complaint, when nobody can produce the substantiation behind a claim that’s already printed on thousands of bags.
The fix isn’t more paperwork for its own sake. It’s deciding, before artwork is finalized, exactly which claims you’re willing to defend and collecting the backup for those claims at the same time you approve the die-line, not after the bags ship. Buyers who treat FSC codes, LOGs, and substantiation records as RFQ deliverables, not afterthoughts, avoid the scramble that follows a CFIA inspection or a Competition Bureau inquiry. shapes this view; the documentation is rarely the hard part. Asking for it before the press run starts is.

FAQ
What documents does a Canadian buyer need for a paper bag’s FSC claim?
You need the supplier’s FSC chain-of-custody code, verified against the FSC database, plus sales documentation listing that code and the specific claim type. Without both, the bag shouldn’t carry an FSC label.
Does Canada require a Letter of Guarantee for food-contact paper bags?
The Food and Drugs Act and Safe Food for Canadians Act require packaging materials to be safe and suitable for their use, and CFIA guidance recommends keeping a Letter of Guarantee or equivalent documentation on file rather than relying on verbal assurance. Store it in your Preventive Control Plan, matched to the specific SKU.
What counts as substantiation for an environmental claim on packaging?
Under the 2024 Competition Act amendments, acceptable substantiation generally follows an internationally recognized methodology, often with third-party verification. A general statement from a supplier without test data or mill records does not meet that bar.
What bag styles does Gather Packaging manufacture in Canada?
We manufacture turn top, serrated top, and tamper-resistant serrated top paper bags, each customizable in size, printing, and finish. Production runs out of our Toronto facility with FSC-certified and recycled material options available.
How long does a custom paper bag order typically take?
Timelines depend on artwork approval speed, plate-making, press scheduling, and finishing steps, with custom colors or specialty handles adding time. Working with a domestic manufacturer typically shortens revision cycles since proofs and corrections don’t cross a border.
