Did You Know?

Transporting live fish (except for live bait) in Ontario is illegal and has the potential to harm ecosystems if those live fish found their way into a new lake. Introducing new fish species like Yellow Perch, Northern Pike, Smallmouth Bass, Rock Bass, Black Crappie and many more, into a lake can disrupt a fragile fishery and cause serious harm. In order to protect Ontario’s lakes and rivers, you should never release any live fish into the water.
