All bass fishing will be closed from May 10th until the 3rd Saturday of June for Largemouth and the 1st Saturday of July for Smallmouth. After those re-openings, the catch and possession limits will be back to the previous season’s numbers of 6 fish for sportsmen license and 2 fish for conservation licence. By the way, this may surprise you, but this latest regulation change is not a new idea to Ontario. Much of the province has an “open all year” bass season. In fact, our feature image of the Smallmouth in this article came before the spawning period on north-west Ontario’s Rainy Lake (with the open all year season). It was released unharmed to feed again and eventually spawn.
