Students at William Lyon Mackenzie Collegiate Institute are unable to properly focus in extreme heat without air conditioning systems in all classrooms and throughout the school.  In the past two weeks, two students have fainted and required Emergency Medical Services to provide them with further care.  The lack of air conditioning systems hinders the education of all students and poses unnecessary health risks as well (such as heat exhaustion, nausea, vomiting, and fainting). The Toronto District School Board needs to take the best interest of its students and provide funding for the necessary implementation of air conditioning systems at William Lyon Mackenzie Collegiate Institute.
