Jurgen Schreiber, the German national and CEO of the Oilers Entertainment Group, is under investigation for his financial records from 2016-2019. Schreiber claimed himself a resident of the Bahamas, but continued to report rental and employment income in Canada. Obviously, the CRA picked up on a tax dodge attempt, and are looking for their cut.
Overall, this seems a classic clear case of a billionaire making a classic tax dodge. Just like the rest of us, and in fact more so than the rest of us, billionaires simply don't like to pay tax - but they have the resources to claim they live in the Bahamas. This will likely have little to no effect on the Oilers at all, but if the ticket prices and beer prices rise again next season, this might be a small indication as to the reasoning.
