Canada just updated its Mexico travel advisory, and you might want to give it a read before you head on your upcoming beach vacation. On Friday, Sept. 12, the Government of Canada added regional advisories in Mexico, warning Canadians to "avoid non-essential travel" in certain areas due to "high levels of violence and organized crime." "In recent weeks, there have been violent clashes between rival armed groups in Culiacán, Mazatlán and their surrounding areas," reads the advisory. The Government of Canada states that authorities in Mexico have made efforts to protect popular tourist destinations, resulting in lower levels of gang-related violence in those areas. Canada recently issued a serious travel advisory for Indonesia, including the popular beach destination of Bali.
