I think it's difficult to pick a particular day or week or month, but I would say that it has been with us in a noticeable way since easily the last couple of years of Mr. Harper's government. It existed before then, but I think, with the passage of time, it has intensified and it continues to intensify.
The most noticeable increase in intensity occurred after President Xi became the leader of China. His activity is much more aggressive and proactive, and that's been manifested in all of the policies of the People's Republic, both with respect to foreign interference and more generally.
