The Timmins – Iroquois Falls Road was first assumed by the Department of Highways on June 30, 1937, shortly after the merger with the Department of Northern Development, at a length of . At that time, the highway travelled along a portion of what is now
Highway 101 west of Timmins. The construction of highway 101 during the mid-1950s resulted in Highway 67 being truncated to a junction between
Hoyle and
Shillington. The route was also diverted onto the Barbers Bay Cutoff; the old routing was redesignated as
Highway 610. Between then and 1997, the highway was long. However, budget constraints brought on by a recession in the 1990s resulted in the
Mike Harris provincial government forming the
Who Does What? committee to determine cost-cutting measures in order to balance the budget after a deficit incurred by former premier
Bob Rae. It was determined that many Ontario highways no longer serve long-distance traffic movement and should therefore be maintained by local or regional levels of government. The MTO consequently
transferred many highways to lower levels of government in 1997 and 1998, removing a significant percentage of the provincial highway network. On January 1, 1998, of Highway 67 was transferred to Cochrane District, leaving only the section between Highway 11 and Iroquois Falls. The section between Highway 101 and Highway 11 is now known as Municipal Road and Jack Pine Road. == Major intersections ==
