Authentication chain for Signature Authentication bound for Canada
Canada is a member of the Hague Apostille Convention — therefore Signature Authentication must pass through: Notary Public → MFA Thailand → Apostille (for Canada).
Once the MFA issues an Apostille, Canada accepts it directly — no further embassy step required, saving 1-2 weeks and embassy fees.
