Open all year in Ontario. Fish shallows with live bait or spoons. Trolling or casting large spoons or crankbaits best for big ones. As in June, very plentiful. Walleye reefs are good for northerns too.
Northerns are somewhat deeper now, but still are easy to find.
Large miinows on reefs work very well. Larger Northerns begin to move to shallows. Excellent month for a trophy. Use larger minnows or lures. Silver is best.
