A video posted to the popular Spotted: STM Facebook page appears to show STM and SPVM officers intervening after one passenger boarded a Montreal bus without a mask. Face coverings have been mandatory on public transit in Quebec since July 13 and the STM tells MTL Blog that the vast majority of passengers are following the rule. But viral posts to social media have called attention to the exceptional cases where transit customers go without a face covering.\nIn the latest video, officers can be heard speaking to the individual on a full bus.\nEditor's Choice: You Could Be Fined $171 If You Hang Your Mask On Your Rearview Mirror In Quebec (VIDEO)\nOne officer says they will give the passenger a mask and instructs them to wait for the next bus. Another passenger, meanwhile, yells at the mask-less person to get off so the bus can depart.\nThe STM confirmed in a statement to MTL Blog that it had heard of this incident, but was unable to provide further details.\nIt also did not provide information on how many such incidents have resulted in law enforcement intervention.\nThe company says it has opted for an approach that favours awareness over "coercion."\nIts inspectors have face coverings available for passengers who don't have one.\nEncore et encore !
