assumed the route of Highway5 south to Jarvis. The route was extended further west in 1930, when the newly-renamed Department of Highways (DHO) assumed the road from Highway8 at Peters Corners to Highway24 west of St. George, as well as the Governor's Road between Highway24 and Highway2 at Paris. The road between Highway8 and Highway24, through Beverley and South Dumfries was designated on June18, while the section of the Governor's Road, along the boundary between South Dumfries and Brantford Township, was designated several months later on September24. These two segments were connected by a concurrency with Highway24. This brought the length of the route to , including the approximately of Bloor Street and Danforth Avenue between Jane Street and Sibley Avenue, within the Toronto city limits. Below the escarpment, the highway followed what is now the Old Guelph Road, meandering into Hamilton. South of Hamilton, the road to Jarvis was numbered as Highway 5 when route numbers were assigned in the middle of 1925. Highway 5 and Highway 6 travelled concurrently from downtown Hamilton to Clappison's Corners. However, on May 25, 1927, several route numbers were revised, including Highways 5 and 6. Highway 5 was redirected west from Clappison's Corners to Peter's Corners to meet Highway 8. Highway 6, in turn, assumed the route of Highway 5 south to Jarvis. Exactly two weeks prior, on May 11, the Department of Public Highways had assumed the road between Jarvis and Port Dover; this also became a section of Highway 6, establishing its southern terminus for the next seven decades. North of the escarpment to Highway 401, Highway 6 follows the same route that it did in 1920, the Brock Road. North of Highway 401, which didn't exist before the 1950s, the route continued through Guelph along what is now Gordon Street, Norfolk Street and Woolwich Street. This section has since been replaced by the Hanlon Expressway, built throughout the 1970s. North of Guelph to Owen Sound, the route also follows the same route as it did in 1920, with some small deviations. The section from Fergus north towards Arthur followed the route was of the old Fergus and Arthur Road Company. A "cheap attempt" at paving had been made in the 1920s. The section was straightened, widened and paved with asphalt-based "penetration pavement" in 1930. On April 1, 1937, the Department of Northern Development was absorbed into the Department of Highways,
