If you're looking at 5-6 year medical schools, it shouldn't be that difficult. It depends on if they view your classes as A-level equivalents. You may need to take an entrance exam, but this is specific for each school (e.g. UKCAT). I believe the deadline is mid-October though. The best thing to do is go to UCAS - Home and look at programs offered. You'll submit your application through this website. As far as where in England, it's really up to you. 5-6 year programmes are the standard; it wasn't until recently that they created graduate entry programmes. London, Oxbridge are probably most competitive, York and Warwick are good. I'm not an expert though. It's best to do your own research based on the geographical region you're interested and send them a mail to find out how many international students they take. Also, since Canada is in the Commonwealth, if you qualify for home tuition, then it's MUCH cheaper!
