Welcome from a fellow Ontarian (live in KW, work in 'sauga)!
You can check the Classifieds forum to see if there's someone selling one, but most of the posters here are US and shipping on something that bulky would be prohibitive. You can also check kijiji or craigslist (or even some of the facebook buy/sell groups) to see if one is for sale in your area, and I've even seen one or two turn up in pawn shops.
If you're looking to buy new, have a few hundred to spend, and want something both proven and bombproof, I highly recommend you go to D'ornellas Cycle and buy a Kurt Kinetic Road Machine. I've had one for about 7yrs now and it's easy to set up, gives smooth resistance with a realistic power curve, and hasn't needed a single bit of maintenance through several thousand kilometers. D'ornellas had the best price in Ontario - if not Canada - when I got mine.
You can choose between fluid, wind or magnetic resistance when buying a trainer. Wind will be noisy and disruptive to the environment around the trainer - if you have a pet it will hate you. Magnetic resistance trainers can be had relatively cheaply but many do a poor job of replicating realistic power curves. Fluid trainers can fail and leak. There is a whole new wave of trainers out there (wahoo kickr and its ilk) that I don't really know much about, but they tend to be even more expensive than the Kurt Kinetic or Cyclops Fluid 2, which are both proven reliable models.
Basically any trainer will fit a bike with a 700c (standard road bike) wheel. Some may need a specific skewer for the rear wheel to connect securely (KK comes with one) or you may need an adapter if you're trying to ride a 26" or 27.5" mountain bike.
Also I highly recommend buying a trainer-specific tire for the rear wheel - something like the Continental Ultra Sport or the Vittoria Zaffiro Pro Home Trainer (available from MEC
). The resistance builds up a lot of heat and regular bike tires will disintegrate, leaving a huge mess and wasting money. Do NOT, however, attempt to ride a trainer tire outside! The rubber they use is very hard and slick, and you'll be sliding across the pavement in no time. If you've got a few extra $, pick up a used rear rim, tube and extra cassette to build a trainer-specific wheel: I can swap out the rear wheel in under a minute to go from trainer to road or back, and it saves having to un-mount/re-mount the very stiff and snug trainer tire on the rim in the shoulder seasons, or if you can manage to get out for a quick ride during one of our frequent thaws.
