Welcome to One of Ontario's Oldest Houses

Upcoming Events
Located on the shores of the Raisin River, in the quaint community of Williamstown sits one of Ontario's oldest standing homes.  Sir John Johnson, a United Empire Loyalist who moved North to Montreal following the American Revolution, left behind a considerable estate in the Mohawk Valley to found and lead the King’s Royal Regiment of New York. In 1784, he was instrumental in resettling many loyalists in what is now Ontario. Johnson himself built a home and mills on the banks of river between 1784 and 1792.
