katface please be aware that if you apply down the skilled workers route you may be waiting a very very long time. Probably a minimum of five years, quite possibly more. The point requirement was dropped from 75 to 67 a few years back, and the result has been a huge backlog and massive delays. The previous gov't (election imminent) brought in a change to say that in future skilled applicants would be weeded out using an occupations in shortage approach, and it is widely expected that this means you will only get in if you can get a job, and that many applications will be rejected. If the Liberals get back in they have said they will repeal this, so it's all a bit in flux at the moment.
So the recommended route is to find out if your occupation is in demand, identify precisely where that demand lies (for example my dh is in IT, which is a shortage skill for BC, there are lots of jobs in Vancouver, but also lots of people looking, but the smaller towns attract fewer people, so that's where we looked, and dh got an offer in Victoria and one in Kamloops), get hold of as many contacts as you can, ring them up, find out if there are any jobs going, offer to come out and talk to them. If you get any bites, organise your holiday/recce around that. Many jobs aren't advertised, so networking is really important (this is less so in the public sector though).
Should you get lucky the employer then has to get a Labour Market Opinion (LMO) if you fall into an occupation in demand then that's not to onerous, but it takes a few weeks. Then you can either apply to the Canadian immigration in the UK or turn up at the border (known as POE) and get the work permit (TWP), the spouse will get an open permit too, which is good.
Once you are in, get the employer to make your offer permanent, and apply for permanent residency (known as PR). This can be expedited as you have a job already, and usually takes under a year.
So if you really want to do it, and BC is very beautiful so why not, then you have to get active about it, and really check things out. This is a sensible approach in any case, as some people have found that they have waited years to get their PR, sold up, travelled over and then found they either couldn't get a job, or that it wasn't quite what they had expected. Good luck! and do check out BE, people there can answer pretty much every question you may have, and there is a very good Wikki too. britishexpats.com/
