The Globe and Mail reports in its Saturday edition that Home Capital Group (HCG) ($9.27) has plunged by almost 60 per cent and it lost more than $3.5-billion in deposits after the Ontario Securities Commission last month accused it of misleading investors about its probe of 45 outside brokers. A Bloomberg dispatch to The Globe reports that the enforcement underscores the difficulty regulators face in keeping fraud out of the mortgage market, and prosecuting individuals who break regulations. Despite having one of the world's hottest housing markets and $1.45-trillion in mortgage debt, the system of rooting out industry fraud is not keeping up, experts say. Principal brokers have a responsibility to monitor broker and agent compliance, says the Financial Services Commission of Ontario. In Canada, the mortgage industry is overseen by each province, with the Ministry of Finance creating the regulation FSCO enforces in Ontario. Companies have their own risk measures, maintaining an internal list of brokers who have submitted fudged applications, referring to them as "unlucky." Equifax says mortgage fraud jumped 52 per cent last year from 2011, showing the issue may only be growing.
