The majority of the freeways and expressways in Ontario are 400-series highways; there are also some others which do not have that designation. The full list appears below.

The freeway network in Southern Ontario as of 2009, including the 400-series highways (blue), provincial controlled-access freeways not designated as part of the 400-Series system (orange), and municipal expressways (purple)

Full freeways (complete controlled-access)[edit]

400-Series Highways[edit]

Other provincial freeways[edit]

The province also maintains freeways which are up to 400-series standards, yet are not numbered as part of the 400-series network; this is despite some of those freeways exceeding existing 400-series highways in size and traffic volume and despite some of them being connected to the 400-series network. Nonetheless, Ontario freeways do not receive a 400-series number unless they are designed to be complete controlled-access freeways for their whole length; the non 400-series routes listed below have significant open-access portions besides the freeway section, with the freeway segment typically being a small section not at the route's termini.

  • The Conestoga Parkway - Baden to St. Jacobs through Kitchener/Waterloo. It carries the designations Highway 7, Highway 8, and Highway 85. Highway 85's southern terminus is at the part where Highway 7 turns off of the freeway portion, its northern terminus is at Waterloo Regional Road 15 (King Street North), whence it continues as Arthur Street, or Regional Road 85.
  • Highway 6 is a freeway in 3 segments:
    • Highway 403 to Clappison's Corners at Highway 5. This freeway is a newly completed, 2.5 km stretch north of Hamilton. Plans are to eventually continue this freeway north to Highway 401 at Guelph.
    • College Avenue to Paisley Rd. in Guelph, as part of the Hanlon Parkway.
    • Maltby Road to Kortright Road in Guelph, also as part of the Hanlon Parkway. The rest of the Hanlon is an expressway with at-grade intersections. Plans are to eventually turn the entire length of the Hanlon into a freeway.
  • Highway 7 is a freeway in 3 segments, and a fourth segment is in planning:
  • Highway 8 - Highway 401 to the Conestoga Parkway in Kitchener. The freeway portion of Highway 8 in Kitchener is known as the "Freeport Diversion" or the "King Street Bypass" or, by many area residents, as "the Highway 8 Expressway". In 1987, the Freeport Diversion was extended to Highway 401; this extension carried the unsigned designation of Highway 7187 until 2011 when it was designated part of Highway 8. Before 1987, traffic continued on King Street East, an undivided 4-lane arterial road to an interchange with Highway 401. Highway 8 is also a freeway co-signed with Highway 7 on the Conestoga Parkway from King Street to Baden.
  • Highway 11 is a freeway in several segments. (Many of the non-freeway segments from Highway 400 to Sudbury are expressways, with a speed limit of 90 or 80 km/h. These expressways have few at-grade intersections, and mostly use RIRO ramps to connect to intersecting roads.)
  • Highway 17 is a freeway in 2 segments:
    • In Sudbury, from Municipal Road 55 in Whitefish to MR 55 in Lively.
    • The Whitefish to Lively section transitions to a two-lane freeway from Lively to MR 55 west of Coniston. This two-lane segment briefly transitions back to a divided freeway at the Highway 69 interchange, to ease future freeway conversion on the segment; the Ontario government has announced that the segment will be upgraded to full freeway in the early 2010s; these segments may be incorporated into a future expansion of Highway 417. Additionally, the expressway portion of Highway 17 near Sault Ste. Marie could also be upgraded into a full freeway in the future, but currently contains at-grade intersections.
  • Highway 35/Highway 115 is a freeway in 3 segments:
    • Highway 401 at Newcastle to Concession Rd. 3;
    • Concession Rd. 4 to Concession Rd. 8;
    • Wilcox Rd. to Highway 7 in Peterborough.
  • Highway 58 - Thorold (from 406 to Thorold Stone Rd. only) (segment expected to incorporate into medium-term Highway 420 plans)
  • Highway 69 - From Highway 64 in French River to Estaire Road in Sudbury. All of Highway 69 is expected to be upgraded to freeway status and incorporated as part of the 400 by 2021.
  • Highway 85 (see Conestoga Parkway above)
  • Highway 137 - Connection to Interstate 81 in Ivy Lea (from Thousand Islands Parkway to Highway 401 only).
