Ruggie's correct you will get better replies by asking on the Canadian Forum. I can't think off hand of any van conversions that would seat 7. You might be best off buying a dodge caravan, Mazda Ford, GM, Honda,or Toyota van all of which will seat seven and having a tow hitch put on it. That way you can pull a small RV tent trailer or caravan and carry the seven. It's also a better way to go as far as gas (petrol) consumption goes, and you can always leave the RV somewhere while you go exploring in the van.
Just a thought.
