Designations

Constructed in the mid-1830s, the Guy House is designated under the Ontario Heritage Act based on both its historical background and architectural merit.

Historically, Guy House represents what was part of this area's earliest settlement. Guy House was one component of a small community which developed around the bustling harbour of Port Sydenham. In context, Guy House was at this time part of East Whitby Township and pre-dates much of the development taking place a short distance to the north in the village which was soon to be called Oshawa.

Architecturally, the noted restoration architect Mr. Napier Simpson note during a site visit in 1977 that Guy House represents a house of the 1830-1840 period will all the good qualities expected in a Georgian Period home of that era. The wood frame structure and its trim are typical Georgian details. At the present time, very few wood structures remain in Oshawa and in fact it is estimated that Guy House may be the oldest of this design and of that period still existing.

Guy House is a very fine example of an early Upper Canada rural home. Although changes have been made throughout the years, the house still retains its rural mystique and beauty associated with its original use as a lakefront farm home.

Today, Guy House is administered as a museum of local history.
