I understand the present movement is all about inclusion of women and minorities. However, being an official is a very difficult and trying job. Not all can handle the time off their regular job, the mental & emotional pressure of the task, the physcally demanding condition and the ability to withstand constant criticism no matter how perfect the job was done but still remain calm, professional and decisive.
I feel certain that if those groups have reps that are interested and talented enough the CFL would welcome them and ensure the get the expert extra training to do the job, But first they need to take on the job in minor leagues to display their talent and dedication.
When have you seen an official get recognizition for the job they just did during a game (not counting their own group). Then answer the question "when hasn't there been someone (mostly Fans from either or both sides) who didn't criticise those same officials after a game"?
