Park Extension is served by two Montreal Metro stations on the Blue line: Acadie and Parc. It is also served by Parc commuter rail station on Exo's Exo2 (Saint-Jérôme) line. Parc station is adjacent to the old Park Avenue railway station, which operated between 1931 and 1984. It is now owned by Loblaws, which operates a Joe Fresh outlet in the former station hall. The space between the station building and the railway line, where the original platforms were located, is now occupied by a Provigo Le Marché supermarket and its vehicular access. A fence runs along the western border of Park Extension, on the opposite side of L'Acadie Boulevard in the Town of Mount Royal. While the stated purpose of the fence is to prevent children from running into the busy thoroughfare, some have contended that it was built to keep residents of the working-class Park Extension neighbourhood out of TMR. The north–south streets of Parc Extension have the same names as those in line with them in Outremont, south of the railway tracks, from Hutchison Street in the east to Birnam in the west. McEachran Street was renamed L'Acadie Boulevard when the street was widened in the late 1950s. The area covered by the residences in the Town of Mount Royal from L'Acadie in the east to Rockland in the west and between Lockhart in the south to Cremazie in the north was once a 9-hole golf course. The golf course was sub-divided during the 1950s and the fence was erected after all the houses covered the golf course land. This fence originally had several gates built into it, which then became a subject of controversy when they were locked one year at Halloween, preventing children from Park Extension from trick-or-treating in TMR. The Mount Royal town council responded by removing the gates. As of 2007, the gates were restored, with signs stating that this is for the safety of children and pedestrians. The "Commission scolaire de Montréal" (CSDM) operates French-language public schools. The English Montreal School Board (EMSB) operates English-language schools. The Montreal Public Libraries Network operates the Parc-Extension library.
