Hi there - this is a long shot, but I'd love to get some advice on behalf of DC aged 24 who had a holiday job in Canada last year (currently back in UK) and is planning to return to look for work long term and wants to make sure he's paid all his taxes before their deadline of 30 April. I have suggested contacting former employer. Unfortunately the CRA (Canadian REvenue Agency)'s website has no helpline, chat or contact details as far as we can see. Any thoughts gratefully received!
