My recommendation is that Canada join its allies, the United States and the U.K., in proposing sanctions against Russian oligarchs. I've heard this terminology “heavy sanctions” coming from the Canadian foreign minister, which sounds good as a headline, but I think she should add the words “and specifically, we're going to look at sanctioning oligarchs close to Putin.” Those are the words that were said by the British foreign secretary and by President Biden.
I think it would have a very strong impact if Putin saw that all the allies were working together and there was no division in the sanctions or the language of the sanctions.
