# List of controlled-access highways in Ontario

The province of Ontario does not have a single unified network of controlled-access highways or freeways. Although most freeways are part of the 400-series highways, which can be characterized by their high design standard, several other sections of provincial highways are also classified as freeways. Additionally, several controlled-access highways, called municipal expressways, are maintained by municipalities rather than the provincial government like provincial highways are.

## Freeways

The following is a list of freeways in Ontario as defined by the Official Road Map of Ontario published by the Ministry of Transportation of Ontario (MTO). The MTO defines a freeway as a divided highway with at least two lanes in each direction.
