Yesterday I was in a realtors office and saw a plaque that read " We only recommend OAHI Inspectors"
8 1/2" by 11" with a large OAHI logo.
This is a first for me. Has anyone else noticed or heard of this in Ontario?
If it was a framed (black) piece of white paper, those plaques were handed-out a number of years ago. I don’t think it was very popular and did not go anywhere as there was some consternation by management about the plaques. (should that come as a surprise?) 
Personally I don’t see how the Realtor can stand behind that claim particularly if the OAHI inspector(s) they recommend aren’t any damn good.
