Tough to say not knowing the circumstances and time frame. I mean I probably wouldn't uproot my children to move to El Salvador but I probably would move to the US if Canada went full autocratic, I have already considered this.
The biggest stumbling block might not be moving my family (provided I can move to a jurisdiction I find suitable for my family) but the fact that I would not be able to return to see my parents or my kids see them in their twilight years. That's a tough sell. I would need more information and context on the state of the world at that time before I would commit to either option.
