I cover all of Niagara Region. What does that mean? The region covers many townships, including St. Catharines, Niagara Falls, Grimsby, Fort Erie, and more. The map shows the areas included, and the links below will take you to more information about each town/city.
For general information on the Niagara Region, I recommend visiting www.niagararegion.ca. Below are the municipal websites. I hope they will be of use to you. As always, if you have any questions about the area (including specific areas that might work best for your needs, or even great restaurants and places to stay while in town looking at houses), or would like a personal tour, I would be more than happy to help!
