Hi Sweden, Rosskilgour and Herjeet.
I've also been married to my wife for 5 years (i'm canadian) and we lived in the UK the entire time as well. We are still waiting for my wife's CORP (transferred June 19th) but like you guys we could not wait around in the UK, so we moved to Calgary, as I had a job offer to come back to which started Mid-June. My wife and children came over in August and have been here for 2 months now, patiently waiting for London's VO get going.
When I moved here we sent all our belongings with me, well on a boat which arrive in Montreal and then travelled by train to Calgary. There were no issues with this as I am a returning Canadian, moving back to Canada. We just sent clothes, paintings and pictures etc.... no furniture or really big items.
When my wife and daughters came over it all went really smoothly. My daughters had their Certificate of Canadian citizenship so they were Canadians coming to Canada (no issues) and my wife was just coming for a 6 month "visit" and explained to the immigration officer that she was going through the sponsorship process. She did have a return flight booked, but the immigration officer said that if it took longer than 6 months for her CORP to arrive to just come back and get her passport re-stamped.
My wife is actually heading back to the UK for a week on Firday so we were hoping the CORP would be issued by now....
Nothing in this whole process has been an issue other than the slowness of the London VO.
