I find it amazing that Ontario teachers have enough time on their hands to worry about Canada's first prime minister, Sir John A. MacDonald, and whether schools should bear his name.  The suggestion is absolutely ridiculous and has no merit!  We cannot apply 2017 values to the last century, nor should we try.  History cannot be erased.   And if we try to go there, numerous Canadian historical figures will be found culpable.  

Perhaps the Ontario teachers should instead have taken the necessary time to check student's swim tests before the field trip to Algonquin Park during which one teenager lost his life!
