He was born in Picton in Upper Canada in 1819, the son of John McCuaig, was educated there and established himself in business in Picton.[1] He owned steamships that operated on Lake Ontario and Lake Erie. McCuaig served two years as Inspector of Provincial Canals. He ran unsuccessfully for a seat in the assembly for the Province of Canada in 1854.[1] McCuaig was elected to the provincial assembly in a by-election in 1872 but resigned his seat to run unsuccessfully for the federal parliament later that year. He was elected to the House of Commons in 1878 supporting temperance in Prince Edward County.[2]
