Canada requires either an Electronic Travel Authorization (eTA, CAD 7) for visa-exempt nationals arriving by air, or a Temporary Resident Visa (TRV / visitor visa, CAD 100 plus CAD 85 biometrics where required) for all other nationalities. US citizens need neither. Attending, exhibiting at or doing business at a trade show is allowed as a business visit without a work permit, but paid Canadian work or selling goods on the ground requires separate authorisation. Apply 4–12 weeks ahead for a TRV; eTAs are usually approved within minutes (allow up to 72 hours). Carry registration confirmation, an invitation letter and a return ticket for the port-of-entry interview.
Estimated cost: Varies by visa type and nationality (check official site).
Processing: Varies by nationality; apply several weeks before travel.
Government fee CAD 100 (≈USD 73); biometrics CAD 85 (≈USD 62) where required. Business visitors attending or exhibiting at a trade show do not need a work permit. Government fee CAD 7 (≈USD 5). eTA is tied to the passport and is valid for up to five years or until passport expiry. US citizens do not need an eTA or visa.
