Labor relations differ between countries and Canada's system is compared to the U.S., China, and India. In Canada, labor laws are mostly regulated provincially with high rates of strikes, violence, and illegality compared to other nations. Successful labor relations in Canada are exemplified by agreements between unions and companies like Petro-Canada, while failures can result in long strikes like the 2005 college strike in Ontario. International firms have also moved manufacturing to countries with less regulated labor like China for cheaper labor costs and fewer unions.
