Source-derived summary

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.

Highway 527

Secondary Highway 527, commonly referred to as Highway 527 is a provincial maintained secondary highway in the Canadian province of Ontario. It is one of the longest secondary highways in the province; only Highway 599 is longer. Highway 527 spans a distance of 235.1 km (146.1 mi) from a junction with Highway 11 and Highway 17, the Trans-Canada Highway, in the community of Shuniah just outside Thunder Bay, to the small, remote community of Armstrong and neighbouring Whitesand Indian Reserve.

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.

Editorial analysis

Why this record matters

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Mar 15, 2026. The linked authority identifier is Q6638068. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1963, 1969 and 1976.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
