  Other provincial freeways

• 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, 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:
• *Baden to Waterloo ;
• *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;
• *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 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.
• *Highway 400 at Barrie to Penetanguishene Rd.;
• *Line 15 North to Carlyon Line ;
• *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 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 401 at Newcastle to Concession Rd. 3;
• *Concession Rd. 4 to Concession Rd. 8;
• *Wilcox Rd. to Highway 7 in Peterborough.
