I can't speak to the domestic content rules globally, but in terms of restrictions on entry, yes, the OECD study rates Canada as one of the most restrictive developed countries.
When you start thinking of developing countries, they tend to be more open to foreign investment, but that openness often comes with additional rules around joint ventures. The idea in China, for example, is that when a foreign company comes in, it needs to partner with a local company. One of the reasons for that is the transfer of technology.
Just to answer your question directly, among the developed countries, Canada is ranked as one of the more restrictive, mainly driven by these three key, closed infrastructure sectors: telecom, finance, and transportation. So we are restrictive.
