Does anyone have any experience on working in the UK? I have a third class engineering ticket with all the MED's etc, just curious about how the system works when transferring over I guess. I have a UK passport so I'm good on that front, any info at all would be great, even about job prospects there or what to expect etc, thanks!

There used to be a lot of Canadians working in the North Sea employed by British Companies on British Ships, through British Agencies, the North Sea is picking up again so may be worth having a try. They will pay your Air Fares for each trip.
