Canadians with upcoming travel plans to Jamaica may want to read up on the government's travel advisory for the popular beach destination. Ottawa updated the travel advisory for the Caribbean island nation on Monday, warning Canadians to "exercise a high degree of caution" due to the high level of violent crime. This isn't the only recent update to a travel advisory for a beach destination. Last week, Canada issued a serious update to a travel advisory for Mexico. Canadians travelling internationally can sign up for the Registration of Canadians Abroad (ROCA), a free and confidential service that notifies citizens outside the country of an emergency abroad or a personal emergency at home.
