永久居留
Grant married Edith Hutchings in 1909. She was born at St. Mary's, was eighteen years younger than Grant, and was working in Toronto as a stenographer. They had five children born in Minneapolis, Toronto, and Havana. Edith and the children returned to Canada in 1926. Grant returned to Canada from Cuba in 1947 after having lost his sight; he lived for a while with his sister Anna McIlwraith and her family at Aurora, Illinois, but US Immigration deemed him Liable to become a Public Charge (LPC) and denied him Permanent Residence status in that country. He died in 1958 at St. Catherine's, Ontario.
