The family moved to Oakville, Ontario in 1889 but returned to Toronto the following year. He was elected a member of the local post of the Grand Army of the Republic and one of 273 Civil War veterans in Toronto to wear the badge of that fraternity. He was then known as "Captain Abbott", a rank which might reflect his office within the Grand Army of the Republic rather than his actual rank during the American Civil War. In November 1892, Abbott was appointed aide-de-camp on the Staff of the Commanding Officers Dept. of New York. A source of great pride for Abbott and his family, this was the highest military honour ever bestowed on a Black person in Canada or the United States.
