South Africans With Two Passports Travelling to Canada — Which One Do You Use?
“Just use whichever passport is easier” — it’s the kind of confident advice that circulates in dual-national family groups, and it’s exactly wrong. Here’s what’s actually confirmed for South Africans with two passports travelling to Canada.
Do I have to travel on my South African passport?
No. If you hold a second nationality — a fairly common situation in the South African diaspora, whether UK, EU or another passport — you can generally travel on that passport instead, provided it’s genuinely eligible for whatever entry document Canada requires from that country. A South African passport specifically requires a visitor visa to enter Canada; there is no eTA route for it. A second passport from a visa-exempt or eTA-eligible country can open the lighter-touch option.
Does my visa or eTA have to match the passport I check in with?
Yes, and this is the part that actually catches people out. Whichever passport carries the visa or eTA has to be the single passport you use for the whole trip: the same one on the booking, the same one at check-in. Applying for a Canadian visa on your South African passport and then trying to travel on your other passport doesn’t work — the travel document is tied to the specific passport it was issued against, not to you as a person.
But what if I booked my flight on the wrong passport?
Then the booking name and document need to match what you actually present at check-in and at the border. This isn’t a Canada-specific quirk; it’s standard airline and border practice everywhere. If you’ve already booked before realising the mismatch, contact the airline to correct the passport details attached to the booking rather than assuming it will sort itself out at the gate.
Can I enter Canada on a passport other than the one I applied under, if it happens to be eTA-eligible?
Only if that passport itself qualifies for an eTA or is visa-exempt, and only if you actually hold that visa or eTA on that specific document. There’s no substitution where one passport’s eligibility transfers to another — each passport is assessed on its own nationality, independently.
And does an eTA attach to a specific passport, or to the person?
To the passport. An eTA is electronically linked to a specific passport number. If that passport expires or gets replaced, the eTA generally needs replacing too, even though you’re the same traveller. Renew a passport shortly before a Canada trip and forget to check the eTA status, and you can arrive at check-in with a valid new passport and a now-invalid travel authorisation.
What’s the safest way to handle two passports before a Canada trip?
Decide before you book anything which single passport you’re using for the entire trip. Keep it consistent from application through to travel, across the whole file. If your circumstances genuinely call for switching passports partway (a South African passport for departure, say, and a UK one held in reserve), that’s a case-specific question worth putting to a licensed RCIC or immigration lawyer rather than guessing.
