Absolutely, which is why my first point is that we need transparency here. We need to know what's going on.
We have seen examples of where states have gone too far. You don't need to go too far back in history to see pretty extreme examples. I don't think we should be complacent about governments even when they appear to be acting appropriately now. We should have legislated limits on state activities.
When it comes to foreign states, we should be very careful about the extent to which we trust foreign states to handle the information of Canadian citizens appropriately.
