Getting any sort of loan will be a complete nightmare because you will have no CANADIAN credit rating. Even global companies like Citigroup don't tend to recognise accounts from the UK. CIBC would only give me a credit card with $1000 credit if I gave them $1000 as security!
It sounds like you have got Canadian residency (the waiting time is approx 36 months at the moment). As previously stated, unless you have a birthright, you DO NOT have citizenship - yet.
