The Hyde Mill Ruins are located at 0 Ontario Street East, at the foot of Ontario Street East, in Streetsville, in Mississauga. The ruins are of a one-storey stone and brick building that was constructed in circa 1840.

When I went, the street was closed off to go down to it but found a back trail along the river that will take you to it. I have enclosed a map. The ruins themselves are also completely fenced in. I did not see any "No Trespassing" signs, so over the fence I went.

History: Located at the foot of Ontario Street on the banks of the Credit River, the Hyde Mill Ruins were significant to the establishment of both John Hyde(a)s Ontario Mills and the first municipally-owned hydro-electric power plant.

The Hyde Mill Ruins reflect the significant role the milling industry had in the development of Streetsville and its contribution to hydro-electric power. It was the area(a)s first hydro-electric station. Built in circa 1840 by American immigrant, John Hyde, it was one of the later mills to be established in Streetsville. When established the mills were at the height of technology and included a saw mill, grist mill and barracks for the workmen.

The success of John Hyde(a)s Ontario Mills came to a halt when the mill was destroyed by fire in 1867. The site was revived in 1906 with the building of a dam across the Credit River and conversion of the mill to generate electricity. It was the first municipally-owned power plant and supplied Streetsville with hydro-electric power until 1943, when the village joined Ontario Hydro. The power plant continued to provide auxiliary power until 1960.

Of the original mill complex only the ruins of the stone walls remain today. The walls and foundation are of squared rubble, reinforced with both concrete and staggered brick. On the north elevation, openings for a door and two windows remain. The ruins serve as a reminder of the industrial heritage of the Credit Valley.

1298 A really neat place to visit I have been going there half my life as it is two minutes from my house. I would find a way into the second brick building but it seems very well boarded up.... also there is a very neat looking green bubble it looks like that you can see from the road it is well boarded now but i have been in it before and there was just a steel bridge from one end to the other and then on either side it went down extremely deep to the point I couldn't see the bottom with a strong

Unknown user Just a word of warning there seems to be some modern buildings still in use there (garages with new locks and maintained building) and the police regularly drop by, so be cautious.
