While Ontario has led the way in opening its legal online betting market to private competition, sparking an advertising blitz that’s ruffled the feathers of regulators and raised concerns among addiction experts, Atlantic Canada has the highest portion of adults registered to place bets.

That’s according to a recent Ipsos poll suggesting more Canadians than ever are wagering online. The data was collected between May 10 and May 13, from 2,001 Canadians over 18 years old.

Federal lawmakers gave the provinces and territories authority to regulate new forms of gambling last summer, following the passage of Bill C-218, the Safe and Regulated Sports Betting Act.
