Pinnacle has had its Internet Gaming Operator registration approved by the Ontario regulator.
The company, which specialises in esports but has also branched out into the B2B arena, is known for welcoming high-stakes 'sharp' bettors.
As was covered several years ago by the New York Times, however, Pinnacle also has a history as an offshore sportsbook.
The operator now adds the Alcohol and Gaming Commission of Ontario to its list of licensors, which also includes regulators in Malta, Sweden and Italy – but not the UK.
