Before the Civil War, Canada was at the top of the underground railroad. If you made it into Canada, you were safe unless someone came and hauled you back. That was also true during the Vietnam War for draft resisters.
Margaret AtwoodA wave of blood goes up to my head, my stomach shrinks together, as if something dangerous has just missed hitting me. It's as if I've been caught stealing, or telling a lie; or as if I've heard other people talking about me, saying bad things about me, behind my back. There's the same flush of shame, of guilt and terror, and of cold disgust with myself. But I don't know where these feelings have come from, what I've done.
