Have you explored the option of an extended car rental? Hertz has a 'Multi-Month' option, for up to 360 days; Avis calls it a 'Mini-Lease,' Enterprise has a 'Long Term' offer, just to mention a few. It avoids the issues of license tags, purchase, registration, etc. and is designed for accommodate, among others, travelers. The rental agencies offer insurance coverage, should your UK insurer not (and you might be able to downgrade your UK coverage for the period that you're absent, at a bit of a savings).

There are two possibilities to consider - and you didn't specify which one you are after.
You want to ship the vehicle to Canada and use it there, but continue driving with the British plates. In this case you should contact your UK insurance company and extend your insurance to cover you while abroad. This isn't going to be cheap for the whole year and not all UK insurance companies will cover Canada, so you may need to switch one. You may want to start reading with this page: Information for Visitors, Tourists and Temporary Residents Entering Canada with Foreign Owned Vehicles, which covers bringing foreign vehicles into Canada while visiting.
You want to ship the vehicle to Canada and re-register it there to drive on Canadian plates. In this case, you need to investigate whether or not it's even allowed. Usually, most vehicles will be prohibited from being imported into Canada. Read this page: Importing vehicles purchased in countries OTHER than the United States - it'll give you the info on whether or not your vehicle can be imported.
In either way, shipping your vehicle to Canada will be expensive - costing several thousand pounds - and take at least a month or so to get there (unless you are talking about air transport, which will cost tens of thousands of pounds). I strongly advice that you leave you VW in Blighty and instead buy a vehicle in Canada, use it while there and then sell it before returning to the UK. You'll save yourself a lot of money and hassles.
EDIT: Whatever options it is, you'll probably find that a brick-and-mortar insurance agent (either in UK or Canada) will be the way to go.
