Other provincial freeways
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 Regional Road 15 (King Street North), where it continues as Arthur Street, or Regional Road 85.
- Highway 6 is a freeway in 2 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. 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, a fourth segment is in planning:
- Baden to Waterloo (see Conestoga Parkway above);
- Concurrent with Highway 115 from the interchange with Highway 7A to Television Road in Peterborough, bypassing the city;
- Carleton Place to Highway 417 in Ottawa. Part of this freeway segment is still under construction.
- Plans are to upgrade Highway 7 from the Conestoga Parkway eastward to Hanlon Parkway into a freeway, along with the Hanlon.
- Highway 8 - Highway 401 and King Street East 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." Since 1987, the Freeport Diversion has been extended to Highway 401. Though this new section is signed as Highway 8 going westbound and Highway 401 going eastbound, it carries the unsigned designation of Highway 7187. 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 (much 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 intersctions, and mostly use RIRO ramps to connect to intersecting roads.)
- Highway 400 at Barrie to Penetanguishene Rd.;
- Line 15 North to Carlyon Line (Orillia bypass);
- Simcoe County Rd. 169 at Washago to Southwood Rd. at Severn Bridge;
- Hewitt St. at Gravenhurst to Kirk Line at Bracebridge;
- Main St. in Huntsville to Station Rd. in Scotia;
- Highway 552 to Highway 522B (Trout Creek bypass);
- Highway 94 at Callander to Highway 17 in North Bay. The length of Highway 11 from Barrie to North Bay is currently planned to be upgraded to a fully controlled access highway in the long term; no 400-series designation is planned.
- 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 58 - Thorold (from 406 to Thorold Stone Rd. only) (segment expected to incorporate into medium-term Highway 420 plans)
- Highway 85 (see Conestoga Parkway above)
- Highway 137 - Connection to Interstate 81 in Ivy Lea (from Thousand Islands Parkway to Highway 401 only).
These include both municipal-constructed freeways and former provincial freeways downloaded to municipalities.

- Highway 6 - Argyle St. South to Green Rd. (Caledonia Bypass) and from Garner Road near Highway 403 to south of Airport Road in Hamilton. Both of these are two-lane freeways, although expansion is planned.
- Highway 7 - From Monaghan Parkway to Sherbrooke Street (Regional Road 9) east of Peterborough.
- Highway 17 is a two-lane freeway in 3 segments:
- In Greater Sudbury, where the freeway portion transitions to a two-lane freeway (see Highway 17 above)
