Methodology

Official sources only

Rules are built from the Canada Gazette, Part II, the Customs Tariff and CBSA customs notices. We read the official English and French texts; we never rely on news reports or summaries.

A daily pipeline watches these sources. When a new order or amendment is published, it is added to the order tracker and to the review queue.

A person approves every rule

A rule says which goods, origins, end uses and dates an order covers, and what evidence a claim needs. AI may draft a rule from new text, but a rule only goes live after a person at FSRC compares it with the official text and approves it.

Approved rules are versioned with their dates in force. When an order changes, the old version stays on record so that past results remain explainable.

Tested against worked examples

Every rule set is run against a library of worked examples with known answers before release. A release is blocked if any example fails.

Every result is cited and auditable

Each finding stores the rule version that produced it, the order and section it relies on, and the date the rules were verified. If a rule is later superseded, affected findings are flagged.

• No citation, no finding
• Eligibility is decided by written rules, never by the AI; results from rules still being verified are marked “Provisional”
• When facts are missing, the outcome is Needs review

Languages

Canadian federal law is published officially in English and French, and we use those official titles. Spanish texts are unofficial FSRC translations, labelled as such, with links to both official versions.

Limits

Results depend on the facts you provide, including the tariff classification, origin and end use of your goods. They are information, not legal or customs advice. Confirm with a licensed customs broker before filing.
