"Did you read the story, or even the headline.
DeVos "cancelled" her trip, she wasn't banned."

There is a reason that you used italics around the word cancelled, presumably because you know yourself that it wasn't exactly a voluntary cancellation.

From the story:


"There had been a reluctance among public-school officials in Ontario to welcome Ms. DeVos,..." 

"Harvey Bischof, president of the Ontario Secondary School Teachers' Federation, said he was pleased to learn that Ms. DeVos was not coming to Ontario."
After The Globe first reported on her visit earlier this week, Mr. Bischof said in a statement that it was "alarming" the provincial government would allow her to tour Ontario schools.

"I couldn't be more pleased that it's cancelled," he said on Wednesday. "

Hardly a welcoming atmosphere. Small wonder that she "cancelled".
