The Globe and Mail reports in its Tuesday edition that four of the big banks had an idea a few years ago to deal with pesky customer complaints: Instead of using the long-standing Ombudsman for Banking Services and Investments, they would switch to a handpicked alternative to resolve such disputes. The Globe's Rob Carrick writes that on Friday, this self-serving arrangement comes to an end. Muscled by the federal government, Scotiabank, National Bank, Royal Bank and TD return to OBSI. Bank-related complaints jumped over the past year at OBSI, which has more than 1,500 member banks, credit unions and investment companies. The biggest driver of banking complaints: fraud -- a worsening problem that is giving the banks all they can handle and more. OBSI, created in 1996, is where you go after you take a complaint to your bank or investment company and do not get a satisfactory response. If OBSI decides to investigate your complaint and finds in your favour, it can recommend compensation of up to $350,000. The tipping point for banks leaving OBSI was Scotiabank's 2018 departure. In the end, the feds appointed Financial Consumer Agency of Canada to look into the matter, culminating in the banks' Nov. 1 return to OBSI.
