Mary,
As the document was in the Lower Canada records, I would assume that the land was in Lower Canada, if it was granted.
This document was a character reference, not a land petition. The link you provided did not give me the microfilm and page number so I could not look to see if this document was part of another document, like a land petition. It also did not indicate whether or not the listed men were acting through an agent or individually. If it was an agent the petition would have been in his name and the families may have had to buy the land from him. Some settlements were established in this way. If the families were acting on their own there would probably have been a petition page requesting that each member would receive land in the same locality as the others so that they could form a new settlement. They could also each apply for land in their own name but not necessarily receive it in the same area.
Petitions usually indicated whether or not the petition was “recommended” or denied. If it was recommended the petition probably would not indicate where the land grant was. This would have to be found in the land records.
You can find more information about land petitions on my website at http://warof1812cdnstories.blogspot.ca/ in Part 1 of the How To… pages in the right hand column.
