The Greenwood Branch has been designated under the Ontario Heritage Act for its historical and architectural value and interest. The former Pickering School House was built in 1860 and claims Canada's 13th Prime Minister, John George Diefenbaker, as one of its students. The building became the Greenwood Branch of the Pickering Public Library in 1980.

"It's an important building," said Jim Simpson, chairman of the Heritage Pickering Advisory Committee. "The history is important and we want to preserve it."

The designation is in part the result of a report by local historians and Pickering Public Library Board Member John Sabean and Gordon Zimmerman.
