This is actually very very good news for Zen and probably why the share price has been running up lately.  Trebor and Zen are Health Canada approved and these other masks being removed from schools etc are from China.  "Radio-Canada has obtained documents showing Health Canada warned of the potential for "early pulmonary toxicity" from the SNN200642 masks which are made in China and sold and distributed by Métallifer, a Quebec-based manufacturer."  

Thank you for posting this fabulous update!!
