He was born in Grenville County in Upper Canada in 1830. After his studies, he began articling in the law office of William Buell Richards, but, in 1849, he joined the California Gold Rush. A few years later, he headed off to the Victorian Gold Rush in Australia. Finally, he returned to Canada, articled in Sarnia and was called to the bar in 1861. He was appointed crown attorney in Lambton County but resigned in 1867 to run for a seat in the provincial parliament. In October 1872, he became provincial secretary in Oliver Mowat's cabinet. In December 1873, he was named Commissioner of Crown Lands. He became a Queen's Counsel in 1876. In 1878, he introduced an Act to Prevent the Forests from Destruction by Fire, the first forest protection legislation for the province. He resigned in January 1889 due to ill health.
He died in Sarnia later that year.
His son Frederick Forsyth later served in the Canadian House of Commons.
