It’s crazy to me that some schools don’t even have ac. Mini splits are cheap as hell. From an email I got recently:

Provincially, the percentage of schools with more than 25% air conditioning coverage is 44%. Since 2017, the OCDSB has made considerable progress improving the cooling systems in our schools:

70% of schools have air conditioning in some or all learning spaces (an increase from 41% in 2017) 25% are partially air conditioned to varying levels, but not in classrooms 5% of schools have no central air conditioning (a drop from 34% in 2017).
