You can always try to post with a specific title like "Help with ebike wanted in Toronto, ON area, Canada".
Or you could just ask if some nearby ES members would like to meet up and try out each others rides.
It is not clear to me if the best solution is to fix your bike or buy/build a new bike. If you are willing to take a bit of risk you could try your current bike at 48V. You could either try to borrow a 48 V battery or add a 12V battery in series to your exisiting one by buying or borrowing a small 12V lead acid battery. These are found in wheelchairs, motorcycles and computer UPS. Another alternative is an RC hobby 4s lipo pack. If 48V gives you the speed you want you can buy e.g. a Ping 48V, 10Ah battery, or the more expensive but higher power cell_man battery below if you want to upgrade to a more powerful bike later. Then deal with the maintenance on the bike you have. While most 36V controllers will work also on 48V there is a risk that the controller will blow, but I think the risk is pretty small.
If you go for buy/build new I would get something significantly better. Ypedal has an A2B. He wanted to try it on 48V, but not sure if he did.
Personally I think building is a better deal. For the $2000+ of a quality pre built bike you can get a motor kit and battery for around $1000, then have another $1000 for a really good used bike.
I would go for a full suspension bike with enough triangle space for the batteries. Try out several different bikes in bike stores, or if you have the time kijiji/craigslist, to find one that fits you well and rides nicely. I think many people here pay far too little attention to the bike. With patience a good used full suspension bike, that has been mostly standing in the owners garage can be bought for less than 1/2 new price. I paid $850 for the Jekyll below, and have bought other good Cannondales for as low as around $400.
The currently best option for hub motors is the Ezee/BMC/Mac geared hub. Does your hills more efficiently than a comparable direct drive, and is lighter. ebikes.ca sells the ezee and provides Canadian support and warrantly. Various US vendors on the list sells the BMC, and the MAC can be bought from cell_man in China. All are quality products. Cell_man also builds batteries, and is afaik the only current source of triangle shaped batteries. See the downloadable .pdf file here:

The triangular 16s5p battery is $600+ship.
Total e-kit costs could vary from around $1000 (Cell_man mac hub motor+wheelbuild, 4110 controller, triang batt above, ship) to $1400-1500 for a BMC V2S kit from Ilya + above cellman battery or the complete Ezee kit with 48V LiMn batt from ebikes.ca. The Ezee battery and controller are waterproof, but battery does fewer cycles. The A123 cells in the cell_man battery are better both at high loads and low temps than other lithium, and like other LiFePO4 should last 2000+ cycles with is 2 times or more longer than most others.
I built a Cannondale Jekyll with a BMC v2s:
http://endless-sphere.com/forums/viewtopic.php?f=4&t=23518
With a 36V battery it does Canada street legal 35km/h With a 48V battery about 50km/h.
The ebikes.ca ezee has a slightly different motor wind. will go slightly slower.
I use between 15 and 20Wh/km in mixed riding around 30-35km/h average speed and 40-50km top speed.
Where the geared Ezee/BMC/Mac hub really shines over other hub motor alternatives is on uphills and other high load conditions (e.g. acceleration). The graphs below compare the efficiency of the BMC (ezee and Mmac will be similar) with that of a good direct drive (9C) and an the highest efficiency RC motor currently widely available (Astro). Values below are for an optimized setup (slick tires, tucked rider etc). Average Wh/km will be higher for most builds but the general relationship between the motors will be the same.
