What's the oldest house in Toronto?

There are a few candidates for Toronto's oldest house. Both are from Ward 30. Scadding Cabin (1st picture), on the Exhibition grounds, is said to have been built east of the Don River, south of Queen Street, around 1794 and moved in 1879. The John Cox house (2nd picture)at 469 Broadview Avenue is thought to be from 1807 or before, and is still on its original site.
