R.P. Grant home was built circa 1853 for merchant/politician R.P. Grant. Grant, whose father was a publisher and bookseller, arrived from Scotland in 1835. He married Annie Carmichael, daughter of the founder of New Glasgow. A pro-Confederation Liberal, he was a member of the Legislative Assembly from 1859 to 1863. He was appointed a Senator in 1877. The house is an excellent example of the Picturesque style whose interesting features include a Palladian style window and bargeboard trim.
