As the honourable member has pointed out, there is a range of diplomatic tools that can be used. We begin, first off, simply by reminding all the foreign missions in Canada of their responsibilities under the Vienna convention not to interfere in our electoral processes.
Here we're talking about elections, but when any kind of interference comes to light, as is the case with the recent publicity around police stations, we take it seriously. We refer it to the appropriate authorities. In the case of the police stations, they have been shut down.
There is a tool in the diplomatic tool kit to declare someone persona non grata. That is allowed under the Vienna convention. It is a tool of last resort, because it almost always results in a tit-for-tat declaration of persona non grata that can be asymmetric, and that is often not in anyone's interest.
Thank you.
