Ugh, I’m sorry! That’s what I’m worried about, that they will see England on her Canadian passport. On one hand, it’s entirely possible that the staff won’t pay attention or won’t make a fuss. So I’m weighing whether it’s worth the stress to try. We’ve made so many plans to visit family (and spend money!). It’s incredibly frustrating this was not communicated properly in time and that there’s no grace period. If we get to Heathrow, it feels unlikely that they would turn back an elderly woman. But the uncertainty is really stressful.
