Changes in technology and regulation have resulted in an increasing number of trading venues in equity markets in Canada. New trading platforms have intensified price competition and have encouraged innovation, and they do not appear to have segmented trade. But the increasingly complex market structure has necessitated investments in expensive technology and has introduced new operational risks. Regulatory responses should be carefully adapted to retain the competition and innovation associated with this market fragmentation.

The financial transaction tax (FTT) is a policy idea with a long history that, in the wake of the global financial crisis, has attracted renewed interest in some quarters. This article examines the evidence of the impact of an FTT on market quality and explores a few of the practical issues surrounding the implementation of an FTT. Proponents argue that an FTT will generate substantial tax revenues and reduce market volatility. The majority of the empirical evidence, however, supports the arguments of opponents of the tax who assert that an FTT reduces volume and liquidity and increases volatility. In addition, there are numerous challenges in implementing an FTT, which may reduce the intended revenues. Whether an FTT is beneficial hinges on its effect on market quality and its ability to raise revenues. However, there are many unanswered questions regarding its design.
