Mackenzie House and Family
Constructed about 1861, this house is a fine example of a blend of several Revival styles termed Ontario Classic Architecture, popular throughout the province during the second half of the nineteenth century. It was built for John Mackenzie, a prominent local merchant and member of the Scottish immigrant family that had settled in Port Sarnia in 1847. By the 1860's he and his six brothers had become firmly established with extensive business interests throughout the region. Hope and Alexander, the two most politically active brothers, developed Lambton County into a Reform stronghold and exercised political leadership over much of southwestern Ontario. They were elected to Parliament, and Alexander Mackenzie served as Canada's second Prime Minister from 1873 to 1878.
