The Canadian Securities Administrators (CSA) is giving trading venues and investment industry firms more time to consider the possible ramifications of a planned pilot study that would curb trading fee rebates.

Responding to a request from the TMX Group Ltd., the CSA announced on Thursday that it’s pushing back the deadline for the comment period on its proposed pilot study, which would test the impact of imposing regulatory restrictions on maker-taker trading fee models, to March 1 from Feb. 1.

Last week, TMX Group asked the CSA in a letter for more time to analyze and provide feedback on the plans, arguing that “The proposed pilot has the potential to materially impact equity market structure and Canada’s capital markets, including marketplaces, dealers, investors and issuers.”

The CSA is planning to co-ordinate its pilot study with a similar initiative from the U.S. Securities and Exchange Commission (SEC).
