Shameful.  It's unbelievable that Air Canada objected to their staff wearing poppies. My 91 yr old father, a WWII Lancaster Bomber pilot who died three years ago, would have been shocked, disappointed and saddened by that decision. It was bad enough that Canada failed to recognize the WWII bombardiers until just recently, but if he knew an airline industry purposely failed to recognize our vets, it would have hurt his heart to know that yet again, Canada is failing in one way or another to recognize veterans.  
It's obvious they only changed their minds after realizing what a poor image that decision would create. 
One has to wonder what kind of mental midgets they have working as executives at Air Canada.
