Tony: Asked about any distinctive patches, etc. for the Calgary Fire Department Aquatic Rescue. They don't wear anything other than the standard CFD patches, with the exception that their jump suits have block letter "Aquatic Rescue" across the back. Here's the link to their page on the City of Calgary website:

Hope that's of use to you. Cheer, DS.
