Would their be similar objections if a British or American firm had made the investment? If we are going to have an open economy we are going to have investment from the largest economy in the world. Chinese investors are aware that the Chinese economy is going to see growth slump to 1-2% per year over the next decade and want to diversify their holdings. Canada is the best positioned company in the world - stable government, lots of space, reasonable economic growth. China does have serious problems with (i) transparency and (ii) its own regulation of foreign investment. That is what we should be concerned about.
