Sunnyside Amusement Park
former amusement park in Toronto, Canada
Sunnyside Amusement Park (also known as Sunnyside Beach Park) was a popular amusement park in Toronto, Ontario, Canada, that ran from 1922 to 1955, demolished in 1955 to make way for the Metro Toronto Gardiner Expressway. It was located on the Lake Ontario waterfront at the foot of Roncesvalles Avenue, west of downtown Toronto.
The name 'Sunnyside' was the name of a local farm owned by John George Howard, which was situated just to the north, on the location of the current St. Joseph's Medical Centre. Sunnyside Avenue runs north–south from that location north to Howard Park Avenue today. John Howard is also famous as the original landowner of the nearby High Park.
Construction
Prior to the construction of the park, the shoreline was a narrow stretch immediately to the south of the 1850s-era rail lines. There was enough area for a restaurant and a small fenced off area was provided for changing into swimwear. To the east, the club-house of the Parkdale Canoe Club jutted out into the lake.
A plan was developed in 1913 by the new Toronto Harbour Commission to improve the shore lands from the foot of Bathurst Street to the Humber River.
