While I think the extent of this problem, almost surely foreseeable at some level, is not excusable.......
If we're going to be even-handed, its my recollection that as many as 1/2 the schools in the TDSB don't have air conditioning.
There are still some older hospitals that don't have a/c in patient rooms.
Public housing doesn't normally have a/c
And private rental housing isn't required to either, there is no Max. temperature in the by-law governing housing.
We have to make up our mind as a society as to whether maximum temperatures are a right; and if they are, we will have to consistently demand this of both the public and private sectors.
I'm all in favour, as I'm probably more heat-sensitive than the average.
I'm just lucky enough to be able to afford a/c.
That said, it can hardly keep up in this weather.......its 25C right now at my place w/humidity running in excess of 70, that despite a/c!
