In 1984 Habitat's most famous volunteer, former U.S. President Jimmy Carter, along with his wife, Rosalyn, participated in their first Habitat build project. Their personal involvement in Habitat brought the organization increased visibility and sparked interest in Habitat's work throughout North America and around the world.

In 1985 the movement spread to Canada with the formation of the first Canadian affiliate in Winkler, Manitoba. From these simple beginnings the Habitat for Humanity movement in Canada has grown to 72 affiliates in 10 provinces and two territories and has been successful in placing more than 1,400 families into new homes.

Habitat for Humanity now spans over 90 countries and is responsible for placing over 225,000 families into new homes around the world.
