@matigo Well I am a Canadian citizen so that would be the most straightforward path. I don't really fancy living in a Vancouver, but that's where I have the most family so it would be my first stop.
However, my third passport is the British National Overseas — currently one of the less useful booklets in the world, but Dominic Raab and Boris Johnson have committed to making it more useful regarding right of abode/citizenship in the UK if the things keep going down the same path. London is an attractive place to live.
Currently looking at tax implications for me opening a bank account in Canada and just holding a minimum deposit there. Also looks like there are a few UK banks (like Monzo) which don't require you to have residency in the UK, or even UK ID, as long as you can provide some UK address for them to send you a card; I'll try to open one in the near future (once the BNO passport gets renewed) and also keep a minimum deposit.
I won't be moving my assets out just yet (I don't have the energy to handle capital gains declarations etc. for multiple jurisdictions, nor do I want to pay tax if I can help it) but it will give me great peace of mind to have at least one bank account elsewhere that I can transfer everything to, when it comes to it.
It has always been "when", not "if", for me. The agreement expires in just 27 years; even with the amount I drink, I'll probably still be alive at that point. Even when things were just dandy here, I had long committed to shifting my assets starting from 2040 and fully leaving by 2045. This has been on my mind for almost a decade now — a shame that the timeline seems to have been fast-forwarded so much, but it may be a blessing in disguise. Never hurts to prepare yourself earlier.
