He was born in Montreal, Lower Canada in 1830, the son of Thomas White, a leather merchant who came to Canada from Ireland in 1826.

He moved to Quebec City in 1851 when that office moved there. In 1852, he assisted Stewart Derbishire in editing the Canada Gazette. He married Esther Vine at Quebec in 1853. Later that year, he founded the Peterborough Review with his brother-in-law. He also served as reeve of Peterborough.

In 1864, he moved to Hamilton and took over the operation of the Daily Spectator and Journal of Commerce. In 1870, with his brother Richard, he bought the Montreal Gazette.
