SEDEX (Supplier Ethical Data Exchange) is a global not-for-profit membership organization that helps businesses manage and improve responsible and ethical practices in their supply chains. Founded in the UK, it is now used by over 85,000 members across 180 countries, making it one of the most widely adopted supply chain transparency platforms in the world.
At its core, SEDEX is a secure online platform where suppliers share data about their operations with the brands and retailers that buy from them. Instead of responding to hundreds of individual buyer questionnaires, a supplier registers on SEDEX once and shares their compliance data with all connected buyers simultaneously. This saves significant time for suppliers while giving buyers consistent, comparable data across their supply chains.
For Canadian businesses, particularly food manufacturers, packaging companies, clothing producers, and distributors, SEDEX membership is increasingly becoming a non-negotiable requirement to supply major retailers and global brands. If your buyers are based in the UK, EU, US, or if you supply large Canadian retailers, the question is no longer whether you need SEDEX. It is simply a matter of when.
SMETA (Sedex Members Ethical Trade Audit) is the audit methodology developed by SEDEX. It is not a certification in the traditional sense but rather a standardized audit format that allows businesses to demonstrate their ethical and social compliance practices in a way that is recognized and accepted by buyers globally.
A SMETA audit is conducted by an accredited third-party auditor who visits your facility, reviews your documentation, interviews workers, and assesses your practices against the SMETA standard. The audit report is uploaded directly to the SEDEX platform where your buyers can access it - eliminating the need for multiple audits for different buyers.
SMETA is currently in its 7th version, SMETA 7, which introduces updated requirements around environmental sustainability and modern slavery, reflecting growing global expectations from consumers and regulators alike.
SMETA audits come in two formats, 2-Pillar and 4-Pillar, which differ in the scope of what is assessed.
The vast majority of Canadian businesses being asked to comply today are required to undergo the 4-Pillar audit. Walmart, Loblaw, and most global brands have moved to requiring the 4-Pillar standard as a minimum. If your buyer has not specified which format they require, it is safe to assume they want 4-Pillar.
If you supply products or services to any of the following, there is a strong chance you will be asked to join SEDEX and complete a SMETA audit:
Even if your current buyers have not yet asked for SMETA compliance, preparing now puts your business ahead of the curve. The trend is clear. Ethical trade requirements are expanding across all sectors, and proactive compliance protects your supply chain relationships.
Register at sedex.com as a supplier. During registration you will receive a ZC number (Company Registration) and a ZS number (Site Registration) for each facility you register. These numbers are unique identifiers that your buyers will use to link to your account.
The SAQ is mandatory for all SEDEX members. It is a detailed questionnaire covering all four pillars - Labour, Health & Safety, Environment, and Business Ethics. You must complete the SAQ before any SMETA audit can take place. Print a PDF copy to give to your auditor on audit day.
Once registered, your buyers can link to your SEDEX account. They will use your ZS number to find and connect to your site. Once linked, they can see your SAQ responses and any audit reports uploaded to your account.
Engage an accredited SMETA auditor or audit company to conduct your audit. The audit is typically semi-announced - you are given a window (e.g. May 16 to June 16) within which the auditor will visit, with final confirmation a few days before.
Before the auditor arrives, a gap analysis identifies exactly where your business falls short of SMETA requirements. This is the most important step - walking into a SMETA audit without a gap analysis significantly increases the risk of non-conformances and a failed result.
One advantage for Canadian businesses is that many SMETA requirements align with existing Ontario and federal Canadian legislation. Companies that already comply with the Employment Standards Act (ESA), the Occupational Health and Safety Act (OHSA), and the Ontario Environmental Protection Act will find that a significant portion of SMETA requirements are already met.
However, SMETA goes beyond what legislation requires in several areas, particularly around documentation, worker awareness, grievance mechanisms, and supply chain transparency. Many Canadian businesses that are fully compliant with the law still have significant work to do to pass a SMETA audit.
This is why a gap analysis conducted by an experienced consultant - rather than a self-assessment - is the most reliable way to understand exactly where you stand before the auditor arrives.
Canadian businesses preparing for their first SMETA audit often underestimate the documentation requirements around worker awareness and grievance mechanisms. Even when pay, working hours, and safety conditions are genuinely good, a lack of written records and worker knowledge of their rights can result in significant non-conformances. Our detailed SMETA audit preparation guide walks through every area of the audit and what you need to have in place before the auditor arrives. For businesses new to social compliance broadly, our social compliance overview explains how SMETA relates to SA8000, BSCI, WRAP, and other common standards.
SEDEX membership and SMETA compliance are no longer optional for Canadian businesses supplying major retailers and global brands. The process begins with registering on the SEDEX platform, completing the SAQ, and conducting a thorough gap analysis before the audit window opens. Starting this process early - ideally 6 to 8 weeks before your audit window - gives your business the best chance of a clean first-time result.
