Here's a breakdown of his key explorations in that time period:

* 1603: He first explored the coast of Nova Scotia and established a settlement at Port Royal.

* 1604: He explored the St. Lawrence River, reaching the site of present-day Montreal.

* 1608: He founded Quebec City, which became a key French outpost in North America.

* 1615: He explored Lake Ontario and Lake Huron.

* 1627: He was captured by the English during a conflict over the fur trade.

* 1632: He returned to Quebec City and continued to explore and map the region.

It's important to note that Champlain's explorations were not limited to the eastern shores of Canada. He also ventured into the interior of the country, making significant contributions to the understanding of the geography and indigenous peoples of the region.
