Foreign ownership of companies of Canada

Foreign ownership of companies of Canada has long been a controversial political issue in Canada. Concerns regarding foreign ownership generally pertain to ownership of previously 'Canadian' assets by individuals or companies based in countries outside of Canada.
The exact definition of "foreign-owned" is the subject of debate. This article uses the working definition for foreign ownership. 
Historically, foreign ownership was a political issue in Canada in the late 1960s and early 1970s, when it was believed by some that U.S. investment had reached new heights (though its levels had actually remained stable for decades), and then in the 1980s, during debates over the Free Trade Agreement.
But the situation has changed, since in the interim period Canada itself became a major investor and owner of foreign corporations. Since the 1980s, Canada's levels of investment and ownership in foreign companies have been larger than foreign investment and ownership in Canada. In some smaller countries, such as Montenegro, Canadian investment is sizable enough to make up a major portion of the economy. In Northern Ireland, for example, Canada is the largest foreign investor. By becoming foreign owners themselves, Canadians have become far less politically concerned about investment within Canada.
Of note is that Canada's largest companies by value, and largest employers, tend to be foreign-owned in a way that is more typical of a developing nation than a G8 member. The best example is the automotive sector, one of Canada's most important industries. It is dominated by American, German, and Japanese giants. Although this situation is not unique to Canada in the global context, it is unique among G-8 nations, and many other relatively small nations also have national automotive companies.
Ways & means.
The foreign company often needs to incorporate a special-purpose subsidiary in Canada, in order to control its investment. The New Brunswick Business Corporations Act, the Nova Scotia Companies Act, the Quebec Business Corporations Act and the British Columbia Business Corporations Act make no stipulations that resident Canadians be directors. New Brunswick provides that Extra Provincial Corporations need only have an "attorney for service" resident in that province. 
Unlimited liability corporations can exist in Alberta, British Columbia or Nova Scotia. This form is particularly convenient where the parties are well-established and in no danger of insolvency. Alberta requires the derisory fee of 
CAD$100 to establish this form. In most other provinces, the legislation is significantly more restrictive.
