Re: ?
The story is not going to make any sense to you if you don't live in Canada and been following the Canadian news. This story doesn't mention any of the background to this announcement but instead goes on about completely unrelated American issues, so there's no reason why you would understand it.
One of the top long running stories over the past couple of years has been about security problems originating in foreign countries. The Government of India have been running around assassinating Modi's political critics in Canada, Saudi Arabia and Iran have been doing their own dirty deeds, and Chinese people have been saying negative things about Canadian politicians on WeChat.
A long running revue committee is just wrapping up their report on all this, and so the government have to be seen to "do something" in order to cut off the press reaction.
Now they've "done something" and so the whole thing can be put behind us and we can get on to the next issue. India will still murder Modi's political critics in Canada, Saudi Arabian security agents will continue to show up at the airport in Toronto with bone saws in their luggage and evasive stories about the reasons for their visit to Canada, and Chinese people will still call Canadian politicians insulting names on WeChat, but we are now safe from, well, something or other.
It's like the Huawei / Meng story from a few years ago. If you didn't follow the Canadian reporting on what actually happened you ended up reading the wildly distorted and inaccurate version circulating in the international press and so would have no idea what was going on or how it all started or ended.
