Your Guide to Using the Fish ON-Line Mapping Tool

"

"This tutorial shows anglers the terrific features and information at their fingertips with the MNR's new Fish ON-Line mapping tool.
http://www.web2.mnr.gov.on.ca/fish_online/fishing/fishingExplorer_en.html

Using the Fish ON-Line interactive map you can learn which fish are in which lakes, find stocked lakes, identify Fisheries Management Zone boundaries, locate ServiceOntario offices that sell fishing licenses and get directions to the lake of your choice.
In less than seven minutes this overview will show you how to check out your favourite lakes and find the next great place to fish, whether searching by fish species, waterbody, GPS coordinates or distance from a city."
