UK/Canada double tax treaty

I am returning from Canada to live in the UK in early 2025, and am retired. I currently have a Canadian state pension (CPP) and a Canadian private pension, that pay me monthly. In November, 2025, I will start to receive my UK state pension. I also have investments in Canada, that generate a fluctuating income, based upon market performance. Given that my only UK derived income will be from my UK state pension, can I just submit my usual Canadian tax return and not a UK return ?

Hi Bobmoore,
You will need to have a look at the tax treaty that exists between the UK and Canada and review article 17 relating to pensions.
It confirms that your Canadian pension and State Pension are taxable only in the UK.
You will have to complete a Self Assessment tax return every year to declare these foreign pensions.

Thank you.
