This was shown repeatedly in Ontario fire and police departments a decade or so ago.

Some grads from Fanshaw College (I believe) Fire program (who also had 4 year undergrad degrees) lost to sons and nephews who had inferior qualifications at various departments in the province the Fanshaw grads had applied to.

While I believe they won their suit, I doubt if much has changed throughout the province....
