Every box, mailer, and poly bag you ship is now someone's financial responsibility, and as of 2026, in most of the country, that someone is you. Municipalities used to absorb a share of packaging recycling costs. That share is gone in Ontario, and Atlantic Canada moved to the same model in the past two years.
Quick answer: Ontario's Blue Box Regulation reached full producer responsibility on January 1, 2026, meaning producers now cover 100 percent of residential packaging recycling costs. Nova Scotia's own EPR program started December 1, 2025, joining New Brunswick, which switched in 2023. If you are the Canadian resident brand holder, importer, or in some cases the retailer, of packaged goods sold into these provinces, you likely need to register, report, and pay stewardship fees, unless your revenue or volume falls under a provincial exemption threshold.
01. The Quick Answer
Extended Producer Responsibility, or EPR, is the regulatory model that makes the business supplying packaging financially and operationally responsible for its collection and recycling, instead of the municipality the customer lives in. Ontario finished its transition under Regulation 391/21 on January 1, 2026. Nova Scotia launched its own program on December 1, 2025. New Brunswick has run one since November 2023. All three are managed provincially, with Nova Scotia and New Brunswick sharing a single producer responsibility organization, Circular Materials Atlantic.
Why it matters: a manufacturer, wholesaler, or DTC brand based in Atlantic Canada is not exempt just because the home province's program is newer or smaller. Shipping into Ontario, the largest population province, means Ontario's fully funded EPR rules apply the moment a package crosses that border.
02. At-a-Glance: Ontario, Atlantic Canada, and Federal Packaging Rules
| Factor | Ontario | Nova Scotia and New Brunswick | Federal Plastics Registry |
|---|---|---|---|
| Effective date | Full producer responsibility since January 1, 2026 | New Brunswick since November 1, 2023, Nova Scotia since December 1, 2025 | Phase 1 reporting active for 2024, 2025, and 2026 calendar years |
| Administered by | Resource Productivity and Recovery Authority (RPRA) | Circular Materials Atlantic, the shared PRO for both provinces | Environment and Climate Change Canada (ECCC) |
| Who is obligated | Canadian resident brand holder, then resident importer, then retailer, then marketplace facilitator | Same producer hierarchy, applied to goods supplied to NS or NB residents | Anyone manufacturing, importing, or managing 1,000 kg or more of plastic packaging, products, or waste annually |
| Small business exemption | Exempt under $2,000,000 gross annual Ontario revenue, five years of records still required | Thresholds set separately by each province through Circular Materials Atlantic | Exempt below 1,000 kg annually of plastic packaging, products, or waste |
| What you owe if obligated | Registration, annual reporting, and full funding of collection and recycling costs | Registration and reporting, stewardship fees based on material type and weight | Data reporting only, no fees, no recycling funding obligation |
Why it matters: these three obligations run on separate clocks, separate registration systems, and separate thresholds. Clearing one does not clear the others, and a business shipping nationally can owe all three at once.
03. Why This Matters for Atlantic Canada Businesses in 2026
Most Atlantic Canada manufacturers and wholesalers sell well beyond their home province, and Ontario alone accounts for a disproportionate share of Canadian ecommerce demand. Regulation 391/21 finishing its transition on January 1, 2026 means the cost-sharing arrangement that used to soften the impact for smaller producers is gone, replaced by full financial responsibility tied directly to how much packaging you actually supplied.
At the same time, Nova Scotia's program launched barely three months before this is being written, which means many local manufacturers and wholesalers are dealing with an unfamiliar registration process in their own home province at the same moment Ontario's rules matured into full enforcement. That timing is not a coincidence so much as a wave of provinces converging on the same model within a short window.
Why it matters: a business that assumed EPR was an Ontario problem, or a large-manufacturer problem, is now facing the same obligation at home, on a program too new for most accountants or bookkeepers to have flagged it already.
04. Who Counts as a Producer, and Why Marketplace Sellers Get Caught Anyway
The producer definition is built as a hierarchy, not a single test, specifically so that no packaged product reaching a consumer is left without an obligated party behind it.
Canadian resident brand holder, first in line.
If you own or license the brand on the product, and you are resident in Canada, the obligation is yours regardless of where you manufacture or where the customer is located. This covers most manufacturers and private label DTC brands directly.
Resident importer, second in line.
If there is no Canadian resident brand holder, for example you are reselling a product made and branded overseas, the business that imports it into the province becomes the obligated producer. Wholesalers importing finished goods should check this carefully.
Retailer supplying directly to the consumer, third in line.
If neither a resident brand holder nor a resident importer exists, the retailer that sold the product directly to the end consumer inherits the obligation. This is the scenario that catches small Shopify sellers reselling imported goods with no Canadian brand owner behind them.
Marketplace facilitator, for marketplace sellers.
If a small business sells through a large online marketplace, the marketplace itself is treated as the producer for that sale under most provincial frameworks. Selling on Amazon or Walmart Marketplace shifts this specific obligation off you. Selling direct through your own Shopify store does not.
Why it matters: a manufacturer selling both direct through Shopify and through Amazon or Walmart Marketplace can be the obligated producer on one channel and exempt on the other, for the exact same product, in the exact same province.
05. The $2 Million Exemption, and What It Does Not Cover
Ontario exempts a producer whose gross annual Ontario revenue is under $2,000,000 from registration, reporting, fees, and performance requirements entirely. That figure is Ontario revenue specifically, not national revenue, and franchisors are assessed on the gross revenue of the whole system rather than a single location. Even a business that qualifies for the exemption is required to keep five years of records demonstrating the revenue figure, in case RPRA asks for proof.
Nova Scotia and New Brunswick set their own thresholds through Circular Materials Atlantic, and those numbers are not interchangeable with Ontario's. A wholesaler that clears Ontario's exemption comfortably can still owe registration and reporting in Nova Scotia if that province's threshold is structured differently, and the reverse is equally possible.
Why it matters: "I am too small for this" is a claim that has to be checked province by province, not assumed once and applied everywhere the business ships.
06. Ontario's Blue Box Regulation 391/21: What Changed January 1, 2026
Ontario's Blue Box program spent several years transferring cost and control from municipalities to producers in stages. As of January 1, 2026, that transition is complete: obligated producers are 100 percent financially and operationally responsible for residential packaging and paper recycling, which covers everything from the cardboard shipping box to the paper insert and the poly mailer bag, not just the product's retail packaging.
Registration and reporting run through RPRA, the Resource Productivity and Recovery Authority, which has been increasing enforcement activity as the program matures, including compliance orders and administrative penalties against producers that have not registered. For a business that has been shipping into Ontario without registering, 2026 is a meaningfully worse year to be found than 2024 or 2025 was.
Why it matters: the enforcement risk did not appear suddenly on January 1, it has been building for years. What changed is that the program is now fully funded by producers, which raises the financial stakes of staying unregistered.
07. Nova Scotia and New Brunswick: Atlantic Canada's Own EPR Programs
New Brunswick was the first Atlantic province to move to EPR for packaging and paper, transitioning on November 1, 2023, under its Designated Materials Regulation. Nova Scotia followed on December 1, 2025, one of the newest programs running anywhere in Canada as of this writing. Both provinces route registration and reporting through Circular Materials Atlantic, which also serves as the point of contact for producers trying to harmonize their compliance work across the two provinces rather than treating them as unrelated systems.
For manufacturers and wholesalers already working through supply chain and vendor compliance requirements covered in GS1 barcode and vendor compliance, packaging EPR is one more line item that touches the same packaging design and shipping decisions, just from an environmental cost angle instead of a retail onboarding one.
Why it matters: a program launched three months before this article was published has had almost no time to build local awareness. Assuming an accountant or existing compliance process already caught it is a reasonable way to miss a registration deadline.
08. The Federal Plastics Registry: A Separate Reporting Obligation
The Federal Plastics Registry, run by Environment and Climate Change Canada, is not a provincial EPR program and does not replace one. It requires anyone who manufactures, imports, or manages 1,000 kg or more of plastic packaging, plastic products, or plastic waste in a year to report that data, with no stewardship fees attached. Phase 1 reporting is active for the 2024, 2025, and 2026 calendar years, with 2026 data due by September 29, 2027, and later phases delayed to give businesses more time to prepare accurate data.
Why it matters: a business can clear a provincial EPR exemption entirely on revenue and still owe a federal plastics report on weight, since the two thresholds measure completely different things.
09. A Practical Compliance Checklist for Shopify Sellers
Start by listing every province your store ships to in meaningful volume, then check each one against its current EPR status and threshold rather than assuming last year's answer still holds, since Nova Scotia's program alone changed the picture as recently as December 2025. Next, work out where you sit in the producer hierarchy for each sales channel: your own Shopify store, any wholesale accounts, and any marketplace listings, since the obligated party can differ by channel even for the same product.
From there, total the weight and material type of packaging supplied per province over the reporting period, check that figure against the 1,000 kg federal plastics threshold separately, and register with RPRA or Circular Materials Atlantic before a deadline forces the issue. Keep the underlying records regardless of whether you end up obligated or exempt, since proving an exemption requires the same data as reporting would have.
Why it matters: the businesses that get caught by enforcement are rarely the ones who checked and were wrong. They are the ones who never checked at all.

If you are not sure whether your business is obligated yet, the free assessment is a straightforward place to find out.
11. Key Takeaways
- Ontario's Blue Box Regulation 391/21 reached full producer responsibility on January 1, 2026, and producers now fund 100 percent of residential packaging recycling that municipalities used to subsidize.
- Nova Scotia's EPR program for packaging and paper started December 1, 2025, joining New Brunswick, which made the switch back in November 2023. Both run through Circular Materials Atlantic.
- The producer hierarchy usually lands on the Canadian resident brand holder first. Selling through a large marketplace shifts that specific obligation to the marketplace, selling direct through your own Shopify store does not.
- Ontario's small business exemption sits at $2,000,000 in gross annual Ontario revenue. Provincial thresholds are not interchangeable, so qualifying for an exemption in one province does not exempt you elsewhere.
- The Federal Plastics Registry is a separate reporting obligation from provincial EPR, triggered at 1,000 kg of plastic packaging, products, or waste a year, with no fees attached but its own deadlines.
12. Frequently Asked Questions
What is Extended Producer Responsibility (EPR) for packaging, and does it apply to my business?
EPR shifts the cost and operational responsibility for collecting and recycling packaging away from municipalities and onto the businesses that supply packaged goods in the first place. It applies to any manufacturer, wholesaler, retailer, or DTC brand that puts packaging, boxes, mailers, poly bags, labels, and the paper products that come with an order, into the hands of a consumer in a province with an active program. There is no exemption for being an online-only or small business by default. Instead, each province sets its own revenue or weight thresholds, and you have to check whether you fall under one.
Am I a producer if I sell through Shopify, Amazon, or Walmart Marketplace?
Usually yes, and the rules are built specifically to prevent online sellers from escaping obligation. Ontario's regulation uses a producer hierarchy: the Canadian resident brand holder is obligated first, then a resident importer if there is no Canadian brand holder, then the retailer that supplied the product directly to the consumer if neither exists. If you sell as a small business through a large online marketplace, the marketplace itself, not you, becomes the obligated producer for that transaction under most provincial frameworks. Selling direct through your own Shopify store keeps the obligation with you as the brand holder or importer.
Is there a small business exemption from EPR packaging obligations?
In Ontario, yes. A producer with gross annual Ontario revenue under $2,000,000 is exempt from registration, reporting, fees, and performance requirements under the Blue Box Regulation, though you still need to keep five years of records proving your revenue qualifies for the exemption if RPRA ever asks. Nova Scotia and New Brunswick set their own thresholds through Circular Materials Atlantic, and they are not identical to Ontario's number, so a business that is exempt in one province is not automatically exempt in another.
What actually changed in Ontario on January 1, 2026?
Ontario's Blue Box Regulation 391/21 finished its multi-year transition, and as of January 1, 2026, producers are 100 percent financially and operationally responsible for residential packaging and paper recycling, a cost municipalities used to share. For a manufacturer or DTC brand shipping into Ontario, the largest population province in the country, this is the point where registering with RPRA, reporting the packaging you supplied, and funding its collection and recycling stopped being optional or partially subsidized.
What is happening with EPR in Nova Scotia and New Brunswick?
New Brunswick was the first Atlantic province to make the switch, transitioning to EPR for packaging and paper on November 1, 2023. Nova Scotia followed on December 1, 2025, making it one of the most recently launched programs in the country as of this writing. Both provinces are managed through a single producer responsibility organization, Circular Materials Atlantic, which is pursuing harmonized rules across the two provinces rather than two entirely separate systems, though registration and reporting still happen provincially.
Is the Federal Plastics Registry the same thing as provincial EPR?
No, and confusing the two is one of the more common compliance gaps. The Federal Plastics Registry, run by Environment and Climate Change Canada, is a data reporting requirement for anyone who manufactures, imports, or manages 1,000 kg or more of plastic packaging, plastic products, or plastic waste in a year. It does not charge fees and does not fund recycling programs the way provincial EPR does. Phase 1 reporting is active for the 2024, 2025, and 2026 calendar years, with 2026 data due by September 29, 2027. A business can owe both a provincial EPR obligation and a separate federal plastics report in the same year.
What do I actually have to do if I am an obligated producer?
Register with the relevant body, RPRA for Ontario or Circular Materials Atlantic for Nova Scotia and New Brunswick, report the type and weight of packaging you supplied into that province over the reporting period, and pay stewardship fees calculated from that data. If you also cross the 1,000 kg plastic threshold federally, you file a separate report to the Federal Plastics Registry. None of this replaces the others, and each has its own registration process and deadlines.
What happens if a business does not register or report?
Provincial regulators have been issuing compliance orders and administrative penalties against non-compliant producers with increasing frequency as enforcement has ramped up, including penalties that can recover the economic benefit a business gained by not paying stewardship fees. Beyond the direct financial exposure, an unregistered producer that gets flagged during a routine audit typically ends up owing back fees for prior reporting periods on top of any penalty, which is a materially worse outcome than registering on time in the first place.
EPR thresholds, effective dates, and producer definitions vary by province and change as programs mature. Confirm your current obligation with RPRA, Circular Materials Atlantic, or a compliance professional before relying on this guide as your final registration record.
