Hi Jeff;
Its not a very good photo, its from a 1947 dated publication I have, showing members of the Canadian Fire Services on parade in London, England, sometime in 1940. It does not show up in this posted image, but there is some type of 'regimental shoulder flash', on their jacket shoulders, possibly baring the title 'Canadian Fire Services' or 'Fire Services Canada'. I'll see if I can being it up a bit.
Cheers
