The Canadian Investment Regulatory Organization’s arbitration program, an often forgotten option for aggrieved investors, is set for an overhaul that would extend the program to mutual fund dealers and their clients. It would also introduce a $350,000 floor for claims, while raising the upper limit to $1 million from $500,000. Positioning the program to deal with disputes involving amounts between $350,000 and $1 million “will provide investors with more comprehensive and flexible avenues for seeking complaint resolution,” the regulator said. The consultation on the proposal runs to Jan. 31.
