It begins at the southern end of Highway 8 in Peter's Corners, next to the junction with former Highway 52. To the west, the road is known as Hamilton Regional Road 5 and proceeds towards Paris. Proceeding east, it passes several houses before crossing a ravine. The highway divides a forest, then becomes surrounded by farm fields on either side. It crosses Spencer Creek as it approaches Brock Road. Spencer Creek plunges over the nearby escarpment at Webster's Falls. Continuing, Highway 5 passes north of several new subdivisions and returns to a farmland setting. It passes through the rural hamlet of Rock Chapel, and then curves to the left on its final approach to Highway 6. East of Highway 6, the road becomes Halton Regional Road 5, but is more commonly known as Dundas Street.
