Canada → Portugal · tax
In plain termsOne treaty, two systems. Portugal counts 183 days or a habitual home; Canada keeps departure tax and OAS geography. The DTA breaks a tie — it does not erase the home rules.
There is a treaty — in force since 2001
An in-force Canada–Portugal DTA exists (yes), signed 1999-06-14 and in force from 2001-10-24. Portugal's own door is more than 183 days — read Portugal tax residency.
Dual residence — a full cascade
Art IV picks one: permanent home → centre of vital interests → habitual abode → nationality → mutual agreement.
Canada-side traps — Portugal does not delete them
Client trapCanada's departure tax, OAS/GIS residency geography and residential ties stay in force (yes). Compare the live beachhead pair: Canada → Vietnam · tax.

Common questions
Is there a Canada–Portugal tax treaty?
Yes. The Convention was signed on 14 June 1999 and entered into force on 24 October 2001. It sets reduced withholding rates and an Article IV residence tie-breaker.
How does the dual-residence tie-breaker work?
Article IV runs the full OECD cascade: permanent home → centre of vital interests → habitual abode → nationality → competent-authority mutual agreement.
Does moving to Portugal switch off Canadian rules?
No. Canada's departure tax (deemed disposition on emigration), OAS/GIS residency geography and the residential-ties test are domestic and survive the move.
