Canada Post is a part of our everyday life, one that we sometimes take for granted. But the Post Office has been part of our country’s history since the 1500’s and has left behind a myriad of records, some of which are genealogically significant. Included are databases of postmasters, both past and present, and documents filed in both Upper Canada Sundries and the Provincial Secretary’s Numbered Correspondence. The Divisional Inspectors’ reports, available online, contain signed petitions requesting new post offices, lists of tenders and the names and wages of the successful contractors on the various postal routes. The Appendices to the Legislative Assembly of Upper Canada and the Sessional Papers contain individual complaints from customers whose mail had been lost, fines levied on negligent letter carriers, and the names of tradesmen who supplied items such as mail bags, candles, pigeon holes, etc. All in all, this is a resource-rich with personal names, and that has the potential for genealogical rewards.
