This is a list of secondary highways in Thunder Bay District, most of which serve as logging roads or provide access to the isolated and sparsely populated areas in the Thunder Bay District of northern Ontario.
The Gull Bay First Nation occupies one of the few permanent settlements on Highway 527, Gull Bay Reserve, situated on the western shore of Lake Nipigon about 70 kilometres south of Armstrong. The highway also passes the start of Highway 811 along its route.
Highway 527 was created in the 1950s as a forest access road and designated Highway 800 in 1963. Throughout the 1960s, the route was gradually extended until it reached what is now Highway 811 in 1969. The route was designated Highway 527 in 1976. Except within the communities of Armstrong and Gull Bay, there are no services or development along this road.

Highway 587 started out as a logging road in the 1800s and a connection to the silver mines at Silver Islet, Ontario.

It remained unchanged from then until 2015, when construction began on four laning Highway 11/17 between Red Rock Road 9 and Stillwater Creek. The route was extended approximately 350 m (1,150 ft) west in June 2019 to the newly opened four lane highway.

"Ontario Secondary Roads Now Designated 500, 600". The Globe and Mail. Vol. 112, no. 33, 119. February 4, 1956. p. 4. 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
