Library and Archives Canada has a listing by surname of land petitions up to 1865. A description of the database is as follows:
“Before the arrival of the Loyalists and British military settlers, the present-day Province of Ontario was an extension of the Province of Quebec. Following the Constitutional Act of 1791, the colony of Quebec was divided to create Upper Canada (today Ontario) and Lower Canada (today Quebec). Many early settlers, both military and civilian, submitted petitions to the Governor to obtain Crown land. Sons and daughters of Loyalists were also entitled to free lands.
The Upper Canada Land Petitions contain petitions for grants or leases of land and other administrative records. This research tool provides access to more than 82,000 references to individuals who lived in present-day Ontario between 1783 and 1865.”
This is not a primary source. It gives a name, date, and the township. To see the actual petition you would need to send for the microfilm.
