Canadian based airlines are starting to resume scheduled flights to and from Mexico. That’s good news for the thousands of Canadian tourists stuck in violent hotspots like Puerto Vallarta and Guadalajara. Many tourists have been sheltering in place since the weekend following fire bombings of cars, shops and buildings - an apparent revenge rampage linked to the killing of drug kingpin ‘El Mencho.’ More than 70 people have died since the violence broke out on Sunday.
