Trefann Court is a small neighbourhood in the eastern part of downtown Toronto, Canada. It is located on the north side of Queen Street between Parliament Street and River Street. It extends north only a short distance to Shuter St. In the nineteenth century Trefann Court was considered a part of the Cabbagetown neighbourhood. It was a mix of industry, linked to the nearby harbour, and working class housing of mainly Irish immigrants. In the post-war years the government began an extensive program of demolishing what were then considered "slums." To the north much of Cabbagetown was leveled to create Regent Park and St.
