Goodrich, Maine is very close to the border with Canada, so I was assuming that there was a guard house/jail of sorts at the time in that location, because it was posted in a newspaper in New Brunswick, Canada, which is right along the border, but yes, I suspect that it was the one in Ontario, too, just because of it saying "Canada", rather than "Nova Scotia", or something more relevant to the area.
I just wasn't confident in that, so I thought that the good people of Wikitree may have some insights. Thank you for taking the time to answer. I appreciate the help.
