You emigrated FROM Canada TO the UK 😳
This is exactly what I thought, but back to the OP.
Having spent quite a lot of time in Canada, what’s so colourful about BC compared to the UK? I accept you generally have a bit better summer, and you have more hippy cafes that can be quite colourful, but you get your fair share of grey skies and rain. Your cities/suburbs are just a grey as ours. Don’t get me wrong, I love Canada and would move there tomorrow, but the bits I have seen aren’t especially colourful compared to the UK. You do have a lot more space and there does seem to be more positive people over there, but that could just my naivety and be the people I’ve encountered.
