There were recently two notable developments with respect to studies documenting high frequency trading in Canadian capital markets.  We have summarized these developments in this piece.

First, the results of a study on the impact of high frequency trading (HFT) on securities trading on the TSX Venture Exchange (TSXV) was recently published by the British Columbia Securities Commission (BCSC) and the Alberta Securities Commission (ASC).  The study tested two hypotheses: (i) that HFT was increasing the volatility in the share prices of issuers listed on the TSXV that were frequently targeted by HFT in comparison to securities that were not frequently targeted by HFT; and (ii) high frequency traders more frequently sell short, or try to sell short, on a downtick following news than other market participants.   The study did not find any evidence to support the first hypothesis and was generally inconclusive as to the second hypothesis. The Public Venture Market Working Group, comprised of the TSXV, the Investment Industry Regulatory Organization of Canada (IIROC), the ASC and the BCSC, conducted the study. 

Meanwhile, IIROC and the Capital Markets Institute at the University of Toronto’s Rotman School of Management also held a public forum on high frequency trading in Toronto on October 19, 2015.  In addition to the study noted above, authors of the following academic papers were hosted as part of a comprehensive review of the impact of HFT and related activity on Canadian equity markets:
