Here's an awesome house hunting tool. It's called collaborate and it allows you to set up custom searches and save them so you don't have to recreate the criteria every time.
The great thing is that the data is directly from the Toronto Real Estate Board and available to you at the same time as your Realtor gets it. Maybe the best feature is that your Realtor registers you and then the rest is up to you with no pesky emails from the Realtor until you decide, if at all, to contact them.

Send me an email at dave@davepratt.com and I'll take care of the rest and I promise not to bother you unless you ask.
