When Stephen Harper tried to revoke citizenship without judicial oversight we have sacked him. I am not quite sure how I feel about this if a court was not involved but I can't find the source. I at least would feel rather uneasy if the gov could just say "this company shouldn't exist".
Edit: ah. Found it. https://www.canada.ca/en/innovation-science-economic-develop...
> In accordance with the Investment Canada Act, foreign investments are subject to review for national security concerns.
I guess that's ... okay. I would still have much more liked a court in the middle but I guess since this is specifically a foreign investment this is ok. The very act https://laws-lois.justice.gc.ca/eng/acts/i-21.8/FullText.htm... begins with:
> Recognizing that increased capital and technology benefits Canada, and recognizing the importance of protecting national security, the purposes of this Act are to provide for the review of significant investments in Canada by non-Canadians in a manner that encourages investment, economic growth and employment opportunities in Canada and to provide for the review of investments in Canada by non-Canadians that could be injurious to national security.
