IRCC has finally officially announced about taking tests outside Canada
Since you can't automatically take the test outside Canada and you'll have to request permission from IRCC by sending an email, some applicants might not be allowed to take the test from outside Canada if IRCC responds negatively. That's my take on this.https://www.canada.ca/en/immigration-refugees-citizenship/services/canadian-citizenship/become-canadian-citizen/citizenship-test/tutorial.html
If you’re outside of Canada
If you get your invitation and plan to take the test while you’re outside Canada, send an email to the address in the Eligibility section of your invitation.
In your email
We’ll contact you with your next steps after we receive your email.
- put “Outside Canada – Citizenship Test” in the subject line
- in the body of your message, include
- your full name
- your application number
- the start and end date for your test
