Find out what life was like for new immigrants arriving at Canada's first quarantine station. It started with a grueling transatlantic sea voyage and the dream of a new beginning.  You disembark at Grosse Île, an island in the the middle of the St. Lawrence River, and enter a quarantine station, set up to fight infectious diseases from 1832 to 1937. Here, Irish immigrants were housed when they came to escape the Great Famine in 1847.
"Open your mouth and say, Aaaahh," instructs nurse Sarah Wade as she examines your mouth and throat. Next, the demanding disinfection process. Step inside showers that once sprayed a mixture of water and mercury bichloride on weary travellers. Don't worry, you'll stay dry! Visit the disinfection chambers and waiting rooms. Be touched by the powerful stories of Grosse Île, exploring the island's over 30 buildings that bear witness to human tragedy and the spirit of welcome and survival.
