probably just a minority... but I am still shocked

I was just watching CBC news a few minutes ago and there was a news clip where the reporter said that emergency services asked the Montreal fire department to go door-to-door to find people suffering from heat exhaustion in their homes as a preventative measure.  The city has set up cooling stations with A/C, water, and medical aid to take in people that do not have a cool place to get out of the 34 degree heat (42 with humidex).  Apparently fire fighters have the right to decline preventative services when the temperature goes over 30 degrees and several Montreal fire fighters have exercised this right and declined to help...  Of course they coupled this clip with an elderly man who was rescued from his home that was measured at 50 degrees... I understand that it is really hot, but isn’t saving lives a big part of why fire fighters join?  Again, I am sure that this is just a small minority of individuals that are refusing to help... but have they no shame?
