The Recycling Regulation defines a "producer" as:
(i) a person who manufactures the product and sells, offers for sale or distributes the product in British Columbia under the manufacturer’s own brand,

(ii) if subparagraph (i) does not apply, a person who is not the manufacturer of the product but is the owner or licensee of a trademark under which a product is sold or distributed in British Columbia, whether or not the trademark is registered, or

(iii) if subparagraphs (i) and (ii) do not apply, a person who imports the product into British Columbia for sale or distribution

The B.C. Ministry of Environment's Recycling Regulation Guide provides the following additional interpretative guidance on how the term "Producer" is applied in practice:

The product producer is principally the first seller of the product in the province. In practice the producer is typically the product manufacturer, distributor or brand-owner. The producer could also be an importer, broker or retailer who sells the product directly to a consumer, including those whose sales are transacted by catalogue or over the Internet.
