Some of you may already be aware of the Ontario's Fish Online website but for those of you who do not, this article was written to provide you with more information on what it offers. The Province of Ontario, and especially the Sunset Country Travel Region in Northwestern Ontario, is one of the best places in North America to go freshwater fishing. Not only are we the most accessible area in Canada where you can travel to fish, but we also have endless numbers (70,000+ at last count) of lakes offering you a variety of species ranging from small fish like crappie and perch, but also the highly-sought-after walleye, lake trout, brook trout and big predators like northern pike and muskie. We are Canada's premier fishing destination for a reason you know and that reason is that when you travel here to fish, you always catch something. 

Beautiful golden walleye are the number one species anglers pursue in Ontario.

What is the Fish Online System

Fish Online has been around for a few years and is a GIS-based mapping system that identifies the different fish species in Ontario Lakes and displays them to you on a map. The great thing about this tool is if you have booked a trip, say to an outpost lake - or any lake for that matter - and you are unsure about what species of fish you can catch, you can use the Fish Online to find out what you are going to catch. This will help you when it comes to your lure selection. If you haven't already booked your trip, and you want to fish for a certain species, then the Fish Online system can show you what lakes have the fish species you're looking for. How cool is that?

A Multi-Purpose Tool

Fish Online is a useful tool because it provides a number of features that are helpful to anglers visiting Ontario. Not only does the tool list the fish species in 16,000 different lakes, but you can also use it to get directions from any point in North America to the lake you are going to fish on. The application also lists Ontario fishing license vendors so if you need to get your license, there is the information. You can also use the app to find lake access points, shoreline fishing spots, and even depth contours. Fish Online is also always up-to-date with current Ontario fishing regulations so that is an extremely useful feature. When using Fish Online to search for lakes you can search: 

  • by the name of the lake or river
  • by the type of fish you want to catch
  • by location and type of sport fish stocked
  • by GPS coordinates

All in all, it's a great tool for any person visiting Ontario on a fishing trip!

Many people from the USA love to fish for big northern pike and we have loads of those!
