Madam Speaker, a public inquiry would be one of the ways. A foreign registry would be another way.
Canada does not have a legal definition for political interference. What we have to do is find other things that happen, where diplomats are potentially breaking other laws, in order for us to investigate them.
A foreign registry would allow us a legal definition, perhaps, of what interference is. The Australians have that. This would be a good model to look at.
If the government were actually serious about this, it would at least engage in conversation and not just disparage members of the House.
