The purpose of this paper is to investigate if there is a differential effect of corporate governance mechanisms on firm risk in Canadian companies cross-listed on US markets and Canadian companies not cross-listed (Canadian only companies). Using a sample comprised of all Canadian companies included in the S&P/TSX Composite Index for the period 2009–2014, this study applies OLS and fixed effect regressions to investigate the effect of corporate governance mechanisms on firm risk. Interaction variables between governance mechanisms and the cross-listing status are used to examine if this effect is different for cross-listed firms.

Results indicate that the effect of board characteristics such as size, independence and proportion of female directors remains the same in both cross-listed and not cross-listed firms. CEO duality and insider equity ownership impact firm risk only in cross-listed companies, while institutional shareholdings, environmental, social and governance disclosure and family control affect firm risk in Canadian only firms. Overall, the empirical results indicate that some governance mechanisms impact firm risk only in firms that cross-list, while others are well-suited for Canadian only firms.
