a few yeals ago, the St-Lawrence and Ottawa valleys were one and part of the Champlain Sea. The weight Ice sheets had pushed the ground down, so when the ice melted the depressed ground flooded for a while until the ground rose back up again.
Modern evidence of the sea can be seen in the form of fossils of whales (belugas, fin whales, and bowhead whales), walruses and other pinnipeds, and marine shells that have been found near the cities of Ottawa, Ontario, and Montreal, and Vermont
