The Ontario Trails Project aims to map hiking, biking and multi-use trails for handheld GPS mapping use.

About the Project

The Ontario Trails project aims to create custom maps for handheld GPS receivers that show hiking, biking and multi-use trails in the Province of Ontario. The project uses GPS tracklines submitted by volunteers, and some government sources of data that are redistributable.

The maps we provide are free of charge, and are intended primarily for use on an outdoor GPS unit. We develop the maps primarily for the Garmin Colorado/Oregon units but others are supported as well.

  • Garmin type handheld GPS units are supported by the project, including the Oregon, Colorado and 60 series. This is a map with a transparent background, so you can load it and it will show on top of your other maps.
  • Magellan type handheld GPS units are supported through a secondary process. We provide shape data, and instructions for you to merge this data with your existing mapsets. Currently tested on eXplorist receivers, using MapSend.
  • Delorme (and other) type handheld GPS units are supported via GPX file distribution.


  • DISCLAIMER: These maps are a reference only. Trail data is submitted by volunteers, and will have varying degrees of accuracy. Always use your head when following these trails, and stay safe. We are not responsible for any problems you may encounter from using this map data! If you find a map inaccuracy, please let us know.

    Have something to contribute?

    To send me a tracklog, simply email it to me at gregory@gregorypleau.com . If you could include the trail name, surface type and intended use that would be a great help. I work best with GPX and Garmin GDB formats, but I'm used to converting data from just about anything.
