Yes. Let me know if I have understood the question correctly.
When Canada imposes sanctions, it necessarily stops or tries to limit trade between it and a foreign country. To stop trade, on the one hand, trade must be happening. On the other hand, the country in question, in this case Russia, must suffer the consequences. However, Canada will also suffer.
An effective sanction will certainly have an impact on the sanctioned state, but the sanctioning state may also suffer the backlash. Relations are bilateral, sometimes multilateral. Canada and any of its allies must forgo trade with Russia. Whether we're talking about imports or exports, we're depriving ourselves of goods or revenue. Of course, if sanctions imposed by Canada or its allies are at all effective, the Canadian economy will feel the impact of them.
Does that answer your question?
