To answer your question directly when the border opens up I would try Lake of the woods in Sioux Narrows Ontario. We stayed at Laughing Waters CG but there are others around including provincial parks. The fishing is very good, caught a lot of walleye pike and Northern pike. The largest was 36 ins and over 15 lbs. I just had a rubber raft so I did not go far from the campsite but those with boats did much better including lake trout down deep. The water in the CG comes from the lake so the water is fairly clean. Saw moose and wolves there when riding my Mtn bike on dirt roads. Met some other campers with boats and fished with them up a river and caught a lot of small mouth bass also. Fist place I camped when I retired you can also rent house boats and fish all day and night. Stayed here twice for a month at a time. Prices were good because of exchange rates. If traveling though Canada I caught 4 lake trout in Muncho Lake in BC and a 7 lb Lake trout in Kulane Lake in the Yukon. Fishing licenses were reasonable.
