People say that these types of measures would result in a change in culture and properly applied governance practices in businesses and in Canada. That's what makes the laws as effective as possible. We know that a law is only effective if people obey it.
Over the years we have seen that the Investment Canada Act has allowed the government to reject three transactions since 2008. Ottawa rejected the bid for MacDonald Dettwiler and Associates from British Columbia by the American company Alliant Techsystems, Ottawa rejected the bid for PotashCorp in 2010, and then rejected the bid for Aecon in 2018.
You see, what this legislation does is essentially serve the interests of the Department of National Defence. When corporate governance goes well, these issues do not end up in the hands of the government; they are resolved at the source. What is more, the benefit of cleaning up corporate governance is that it's the best way to get long-term results on these issues.
