The TMX Group Inc. is planning a series of changes to the fee structure for its TSX Alpha Exchange.

The changes include increasing active rebates for retail orders for equities, eliminating active rebates and lowering posting fees for ETFs, and reducing passive posting fees and active rebates for stocks priced under $1.

TMX is also proposing to extend the Alpha Liquidity Provision (ALP) program that was launched in November 2018 to include ETFs.

In a notice setting out the planned changes, the exchange said they are intended to “enhance available liquidity while also delivering additional savings for cost-sensitive active retail order flow.”

The changes, which are subject to regulatory approval, would take effect on May 1.
