The Apostleship of the Sea (AOS) is an agency within the Roman Catholic Church that serves the people of the sea and their families.

AOS is present in the various ports across Canada. We work in solidarity with all those whose lives depend on the sea, and offer them welfare, hospitality and spiritual support.

Please take the time to explore this site and learn about:

• the history of the Apostleship of the Sea;
• the work that we do throughout various Canadian ports;
• resources available to seafarers; and,
• ways by which you could get involved in the work that we do.
