 In 1793, Lieutenant Governor John Graves Simcoe charged Jones with the surveying and construction of a new road from Lake Ontario to the Thames River. Simcoe employed the Queen's Rangers led by Captain Samuel Smith for the road's construction, from Hamilton to Woodstock. This road would become Dundas Street. The same year, he surveyed Flamborough Township, Beverley Township, Ancaster Township and York Township. Jones spent 1794 surveying Flamborough, Glanford, Binbrook, Delaware, Oxford, Dorchester, Burford, Grimsby and Windham.
