Fishing Regulations

Sustainable Fishing Practices at CVC Parks

Credit Valley Parks offer three different fishing opportunities for the beginner to advanced angler. Take your fly rod to the river, hook a trout in a stocked pond or head out on the water to land a perch, crappie, largemouth bass or pike. Please follow our sustainable fishing practice guidelines.

Voluntary Harvest Limits

We encourage you to follow the Voluntary Harvest Limits posted at our parks as a fisheries management technique. This will help ensure a sustainable healthy fishery for all to enjoy.

Live Bait Ban

No outside baitfish are permitted at CVC parks except baitfish purchased at the Island Lake shop.

Worms, where Ontario Fishing Regulations allow, are permitted as bait at Island Lake Conservation Area and Ken Whillans Conservation Area. Worms are not allowed when fishing the streams at Ken Whillans. CVC does not allow the use of or harvesting of baitfish, frogs, leeches or crayfish in our parks. These regulations protect our valued fisheries resources and protects against disease transfer and the introduction of invasive species.

Garbage Disposal

Pick up your garbage and take home or dispose it properly. Please dispose of your used line in our line recycling stations at our parks.

Avoid Lead Tackle

Use alternatives to lead tackle. Tin and bismuth are good substitutes for sinkers and jigs purchase instead of lead. Lead is poisonous to fish, shorebirds such as gulls and loons, and waterfowl.

Fishing Regulations in the Credit River Watershed

The Province sets rules that anglers must follow when visiting Credit Valley Parks. Refer to seasons and regulations for Fisheries Management Zone 16 at ontario.ca/fishing.

Catch and Possession Limits

The catch limit is the number of fish you are allowed to catch and keep in one day. The possession limit is the number you are allowed to have in your possession:

  • On hand, or
  • In cold storage, or
  • In transit

The possession limit is the same as one day’s catch limit.

  • If you catch a fish and it is eaten the same day, that fish counts towards your daily catch limit.
  • If you have a Sport Fishing Licence that entitles you to possess six Northern pike, and you have two in the freezer at home, you can only catch and keep 4 additional pike.

Fishing Licence

You most likely need a fishing licence to fish in our waters.

  • Most residents of Canada will need a fishing licence.
  • All non-residents between 18 and 65 will need a fishing licence.

Those who qualify to fish without a licence:

  • May fish with the same catch and possession limits as holders of a Sport Fishing Licence
  • Must abide by the same regulations and have the same responsibilities as those who have purchased a licence.
