About The Robert West House

The Robert West Heritage House, as 7780 Yonge Street is known, is the only house in Thornhill to be continuously inhabited by the same family since it was built. Robert Arthur West (1816 - 1884), an English immigrant, came to Upper Canada in the 1830s. 



About Mrs. Keith

Katherine Louisa Keith (nee West) was born in Toronto in 1912. She was the great grandaughter of Robert West and became his last living descendent.


In 2008, with her advancing age, she decided that the best way to ensure that the house was preserved was to donate it 

Pictures of the Robert West House

Thornhill was founded in 1794. Its first settlers on Yonge Street in Thornhill were Asa Johnson (who settled on the Vaughan side) and Nicholas Miller (who settled on the Markham side). Of particular importance was the arrival of Benjamin Thorne in 1820, who was operating a gristmill, a sawmill, and a tannery in the community. The settlement came to be known as Thorne's Mills, and later, Thorne's Hill, from which its current name is derived. More

Pick A Picket Fundraiser - 2022
We are pleased to announce that the new picket fence along Yonge Street has been installed.
Many thanks to all our supporters.
The line of the fence was determined by the location of undergound services.
The fence has to 'weather' over the winter, after which it will be painted white.
The names, submitted by our supporters, are being prepared for installation after the painting.
