Port Maitland The Grand River - Sportsman's paradise We turned in to Port Maitland, which is at the mouth of the Grand River, on September 7th and discovered a sportsman's paradise. The river carries a depth of 14' the whole way of 4 miles to the dam at Dunnville. Several hunting blinds are visible in the thick reeds that edge the river. We can attest to the fact that goose hunting season is under way as we heard shots, behind us, as we passed down the river at dusk in our dingy. We were surprised to learn that Canada Geese are hunted. They need to send a group of these hunters to Toronto Island. There is a large population of Great Blue Heron here - they're still safe, as far as we know. Fishing and boating are also very prevelant.
