As luck should have it, I follow the nf.birds@googlegroups and easily found the name of a person to contact for help with the banding information. I emailed Rob Bierregaard (check out his website here) and he advised me on how to report the banding via the North American Bird Banding Program under the general direction of the U.S. Geological Survey and the Canadian Wildlife Service. When I filed the report I was advised that it could take upwards of 4-6 weeks before I'd hear anything. That was quite an overestimation as I received the certificate via email last night!
Note that, while the sighting was at the corner of Clarke and Fanshawe Roads in London, Ontario the GPS coordinates identify the location as ENE of Fanshawe, Ontario.
