definately the mosquito coils, a light weight headnet, and i find the most important thing is a hanging bug net to hang above your bed. I,ve been to Ontario many times and every year i bring less. You dont say what your gonna fish for. walleye – some 1/4 and 3/8 oz. jigs and a half of crawler is all i ever use. put on a white 4″ mister twister type plastic tail for walleye and pike. Dont over pack on clothes but bring a warm hoody and full rainsuit. If bringing alcohol consider a bottle instead of beer. a case of beer is twenty pounds.
