Not living in Ontario, this is the first I hear about the case, but from this single article, it seems the PC crowd has no qualms about throwing an old woman with some age-related language difficulties under the bus to make some political point mostly demonstrating their moral superiority:

"She said that in a private, hallway conversation with another trustee after a board meeting, she was trying to refer to a parent but did not know her name, and only that she had been featured in stories about children being called a racist word. “In trying to explain that,” Ms. Elgie said, “the words came out wrong, very wrong. As soon as I realized what I’d said, I was mortified.”

Sounds like the typical case where context is deemed irrelevant as long as the magical word was uttered. Sounds like Mao's Red Guards.
