Thank you.
One way to answer that question would be to distinguish between sweeping and targeted sanctions. Sweeping sanctions are sanctions that target a government as a whole, a country as a whole or the economy as a whole. Targeted sanctions target individuals or entities one by one, and you list them.
Sweeping sanctions are, as a rule of thumb—and I'm simplifying it here—extremely labour-intensive. The demand on the intelligence community, law enforcement, the CBSA and so on is huge, because the number of individuals and entities they have to monitor and then potentially enforce sanctions on is huge. We simply don't have the resources for that in a context where, to deal even with non-sanctions issues, we are already overstretched—CSIS, the RCMP and so on.
As a general rule, I would be very reluctant—it's not a blanket “no”—to impose additional sweeping sanctions. I very much support the targeted type.
