• Smythe Park
• Black Creek

Rockcliffe-Smythe is a York neighbourhood near Jane Street and St. Clair Avenue West, where Lavender Creek joins Black Creek on its way to the Humber River. Its story begins with Conn Smythe of the Toronto Maple Leafs. He started a sand and gravel business, later named C. Smythe Limited, and worked a gravel pit northwest of Jane Street and St. Clair Avenue. He owned the company until 1961.

Once the pit was exhausted, its site became Smythe Park, now home to a recreation centre on Scarlett Road. Around it, homes went up after the Second World War as York Township urbanized, including a subdivision Smythe built for war veterans. Because the area was built within the creeks' natural floodplain, the City of Toronto's Rockcliffe flood mitigation project plans wider crossings at the Jane Street culvert and the Scarlett Road bridge over Black Creek. York became part of the amalgamated City of Toronto in 1998.

The Rockcliffe-Smythe tee is for the neighbours of Conn Smythe's old gravel pit, on the banks of Black Creek.
