If you are going to get a power planer and jointer - pretty well needed if you want to use cheaper/more varied supplies of rough sawn lumber - you will want a dust collector to deal with the mess, even if you are not yet convinced of the health issues breathing in wood dust. So put a dust collecter on your list of items to research and plan on two 240volt circuits (one for the dust collector and one for running, one at a time, any stationary woodworking machine that you may eventually acquire).
Further on dust collection.... with power handtools, radial orbital sanders, handheld routers, research online how well they do dust collection. For example, do buy a handheld router that has an integrated dust collection takeoff that attaches to a shopvac. Some ROS attach easily to a shopvac hose; others "only with the help of a bit of duct tape? In buying a new or used tablesaw, anticipate eventual overhead dust collection even if you don't buy a tablesaw that has a blade guard with an integrated dust collection takeoff.
Handheld tools: you live in the GTA: on Sunday, April 1st, in Pickering, the Tools of the Trade interest group, have their sale of used/vintage handtools; there you can pick up a full set of classic, high quality bench planes for around $200. Learn to sharpen
handtools like biscuit joiners and chisels. Handsaws actually work! Read up on adding shopmade holding devices to your existing bench and keep an eye out for a great but cheap bench vise. Before you clutter up your one car bay space with machines, perhaps set it with wiring, insulation, drywall/panelling, etc.
On the other hand, routers are amazingly versatile motor driven tools, doing many (but by no means all) of the joints, etc. that chisels, handsaws and handplanes have traditionally done. Get a book like Bill Hylton's Woodworking with a Router.... like hand driven tools there is learning curve regarding its applications, making jigs plus the more significant issue of safe tool use.
Jointer and Planer: I hear Dan say straight knife jointers are passe but there are lots of us that are not giving them up (because they do a good job, albeit with more noise) and the straight knive jointers that are being given up by people who are "upgrading" present a buying opportunity for you. While I now have an 8" General jointer and 15" stationary 240v. planer, I was able to do 'big' work with 6" Rockwell/Beaver jointer and 10" Ryobi AP10 planer; both are solidly built like the proverbial outhouse and, along with similar used jointers and planers, come on the used market for about $200 and $100 respectively.
Tablesaw: as Rod said, lots of figuring/options here.....I think your inclination toward a used Rockwell Unisaw is sound.... look at Wally of Calgary's picture rebuild of the saw to see the quality machining; even with the downstream addition of a blade guard that provide dust collection you will have a 'forever' tablesaw for less than a thousand....
but don't rule out the Sawstop; ask yourself, if a used cabinet level Sawstop (v. good machining, dust collection, great fence and its amputation proof technology) popped up for under $2000, would you buy it? and do the research and be prepared to move fast if the answer is yes, 'cause such a machine at that price will not be "unsold" for long. Have a list of used tablesaws .....at widely different price points even, that you would be prepared to buy if they came on the market and, if and when it does, move fast. Do your research.
Acquiring hand tool skills, improving your shop space cost very little while you research and keep an eye out for terrific machine tools buys.
