Your refusal letter and your CAIPS notes are full of paragraph codes — short alphanumeric references to specific sections of Canadian immigration law. Here's a quick map of the most common ones, so you can at least recognise the territory before someone walks you through them.
The big five you'll see most often
- R179(b)— Visitor / TRV refusal: officer isn't satisfied you'll leave Canada at the end of your stay. By far the most common refusal in 2026.
- R200(1) — Work permit refusal. Variant R200(3)(a)is a finding that you're unlikely to leave; R200(1)(c) usually means insufficient documentation.
- R216 / R220— Study permit grounds, often around “genuine intent” (see our separate guide on Section 200).
- A11(1)— “Foreign national must establish that they meet the requirements” — used when an officer thinks the burden of proof wasn't met.
- A40(1)(a) — Misrepresentation. The most serious category. We have a dedicated guide on this.
Why a code list isn't enough
Every refusal letter cites a code, but the same code gets used for very different underlying problems. An R179(b) refusal for one applicant might be about thin travel history; for another, it's about unexplained finances; for a third, it's family in Canada creating “dual intent” concerns. The code is the legal hook — the officer's notes are where you find the actual reasoning.
That's why we don't publish a detailed decode of every code online: in practice, decoding requires reading your specific notes alongside the code, in the context of your visa type, country, and history. A generic explanation leads applicants to fix the wrong thing.
Want your specific refusal decoded?When you order CAIPS notes through us, our team reads them against your application file (Tier 2) or writes you a 3–4 page plain-English interpretation tying each code in your file to what the officer actually flagged (Tier 3). Or simply call us — we'll walk through your notes on the phone.
