If you look closely at the document (click on the image to see a bigger version), you will see that the town mentioned is Halifax and the crests are those for Halifax (as it was before 1964) and Nova Scotia. Pencilled annotations state ‘Your crest here’ and ‘Ontario crest here’ and the name Deseronto has been pencilled in next to the main block of text, where it would replace the word Halifax.
What is not clear from the certificate is whether the Town went ahead and ordered their own version of the certificate for servicemen returning to Deseronto. Did any Deseronto veterans receive such a thing? Has anyone seen a certificate like this among the papers of a friend or relative?
