C anada has been losing its attractiveness as a destination for foreign investment compared with other countries and is in no danger of being “hollowed out” by takeovers, a new report argues. While some of Canada’s best-known companies have been targets of foreign buyers in recent years, the country’s overall share of global foreign investment has been falling for decades, harming prosperity by slowing the transfer of new technologies, said a study issued Tuesday by the Montreal-based Institute for Research on Public Policy. Walid Hejazi, an economics professor at the University of Toronto and author of the study, said foreign investment overall has expanded throughout the world in recent decades, but Canada’s proportionate share of it has “fallen precipitously.” In 1970, Canada received 15.7 per cent of total foreign direct investment worldwide, but just 3.4 per cent in 2007.
