From 1832 to 1937 more than four million people sailed across the Atlantic to the port of Quebec with the dream of creating better lives for themselves in the New World. During this period, a tiny island called Grosse Île, located fifty kilometers downstream from the port, served as a quarantine station. Its mission was to prevent ship passengers from spreading diseases to the mainland. This is the story of the island, which served both as gateway and graveyard for the thousands of people who landed on its shores, and of the caring island workers who welcomed them.
