From the crown, Mike, I'm sure it's Canadian and would guess it is a badge worn by representatives of the Dominion Securities Company.
Here's some type I lifted from here and there:
>>>As Canada began to industrialize in the years leading up to the First World War, there was a growing need for capital. During the First World War, the Dominion Securities Company was closely identified with the Dominion government's financing of the war, beginning with the first war loan in 1916. During World War I, Canada was converted to a nation of bondholders - it is estimated that in 1914 there were only a few thousand Canadian bondholders; by 1919, there were over one million bondholders in Canada.
Again in WWII, Victory Loans sales were introduced with several issues... in 1944, Shirley Temple, then 16, helped Prime Minister W.L. Mackenzie King drum up support for the 7th Victory Loan campaign. These campaigns were so successful that after the war they continued and became our beloved "Canada Savings Bond" program.<<<
