Online sports betting and casino games in Canada generated $12.5 billion in revenue last year. But more than half that money ends up offshore, where there are no Canadian taxes, and little to no consumer protections. That's why the province of Ontario opened up its online gambling market to private operators four years ago, and why Alberta is following suit later this year. But for a small but growing number of people, all this gambling has led to financial hardship... or worse.  A recent study suggests the rate of young men contacting Ontario's mental health helpline for gambling-related problems has increased by more than 300 per cent. In this documentary, John Chipman explores the true cost of the rise in online gambling.
