 Budget constraints brought on by a recession in the 1990s resulted in the Mike Harris provincial government forming the Who Does What ? committee in 1995 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 ( downloading ) , removing a significant percentage of the provincial highway network . As Highway 58 had largely been replaced by Highway 406 , the central segment through Welland and Pelham was deemed to no longer serve long @-@ distance traffic , and was downloaded to the Regional Municipality of Niagara on April 1 , 1997 . It now exists as Regional Road 54 along Prince Charles Drive and Regional Road 50 along Niagara Street and the Merrittville Highway .
