Secondary Highway 504, commonly referred to as Highway 504, was a provincially maintained secondary highway in the Canadian province of Ontario. The highway was 26.1 kilometres (16.2 mi) long, connecting Highway 28 south of Apsley with Highway 620 in Glen Alda. The only other community served by Highway 504 was Lasswade.
Highway 504 was established, along with many other secondary highways, in 1956. Originally, the route looped around Chandos Lake back to Apsley. However, the northern portion of this loop would later become Highway 620. During the 1997-1998 mass downloading of Ontario provincial highways to local authorities, Highway 504 was downloaded to Peterborough County and has since been known as County Road 504.
Although Highway 504 no longer exists today, the route it follows is currently designated as Peterborough County Road 504. Despite this designation, a short 200 metres (660 ft) section near Glen Alda lies within Hastings County. The route began at Highway 28 just south of Apsley, and entered the village along Burleigh Street before turning onto Wellington Street. From there, Highway 504 travelled east into the southern fringes of the Canadian Shield, with thick forests surrounding the majority of the route. However, in addition to the hamlet of Lasswade, located around the midpoint of the highway, the route also served cottagers along the southern and eastern shores of Chandos Lake and numerous residences line the length of road. At Lasswade, located at a junction with Peterborough County Road 46, Highway 504 turned north, and meandered towards Glen Alda. There it encountered Highway 620 and ended.
The route of Highway 501 was first assumed by the Department of Highways in early 1956, along with several dozen other secondary highways. It was likely maintained as a development road prior to that. The route travelled in a loop around Chandos Lake, beginning and ending in Apsley. The following year, Highway 620 was designated east from Glen Alda to connect to Highway 62. Highway 620 assumed the northern route of Highway 504, west of Glen Alda, circa 1963. Between then and the 1990s, the route remained unchanged. On January 1, 1998, the entirety of Highway 504, including the section that had become Highway 620, was transferred to the responsibility of Peterborough County.

Two new Ontario road numbers appear on the province's 1956 official road map which will be ready for distribution next week. The new numbers are the 500 and 600 series and designate hundreds of miles of secondary roads which are wholly maintained by the Highways Department. More than 100 secondary roads will have their own numbers and signs this year. All of these secondary roads were taken into the province's main highways system because they form important connecting links with the King's Highways
