UAE and Canada had a falling out, how does this afftect visas?

Hey, I heard that maybe a year or 2 ago Canada and the UAE had a diplomatic falling out due to a fight over airplane flights.
Does anyone know if this affected Canadians travelling to the UAE?

It means that Canadians now need a visa BEFORE entering the UAE

I wouldn't imagine so since they are still actively recruiting teachers from there. At least Abu Dhabi is.
