On July 8 1926, the entire staff of the township of Scarborough and their families had their annual picnic at Silver Fern Park. The July 9 1926 edition of the Toronto Daily Star captured the event in photographs.
I could find no reference to Silver Fern Park anywhere. The town of Agincourt has long since been swallowed up by what is now the city of Scarborough; it is bounded by Kennedy Road on the west, McNicoll Avenue on the north, various streets from McCowan to Markham on the east, and Highway 401 on the south. Presumably, the park was turned into housing developments long ago.
