This RCAF patch from 414 Squadron could be found in use between 1957 and 1964 when the Squadron was disbanded until 1967.  The Crest Craft back-stamp found on the back of this specific style indicates it was manufactured between 1957 to 67. Similar examples exist but are of the stitched variety and probably not manufactured by Crest Craft.
