According to ALLCITYCODES.COM, the area code of Canada is +1, which was adopted in 1947 when Canada switched to the ITU-T E.164 numbering system. The code is divided into two parts: ‘+’ and ‘1’. The ‘+’ indicates that the number is international and the ‘1’ identifies the country as Canada. In Canada, telephone numbers are usually ten digits long and are divided into three parts: a three-digit area code, a three-digit exchange code and a four-digit line number. Area codes indicate the geographic region of the phone number and are used to route incoming calls to their respective locations. Exchange codes identify specific local calling areas within each geographic region, while line numbers identify individual subscribers within each local calling area. Canada has one of the highest mobile phone penetration rates in North America and its population is rapidly increasing their use of telecommunication services such as mobile phones, internet access and other technologies due to advances in infrastructure and technology over recent years. As such, it is important for businesses operating within Canada to ensure they are using the correct area codes when making calls within the country as well as when communicating with other countries around the world. The politics of Canada function within a framework of parliamentary democracy and a federal system of parliamentary government with strong democratic traditions. Canada is an independent nation, but it is also part of the British Commonwealth, which means it recognizes Queen Elizabeth II as its head of state. The executive branch is formed by the Cabinet, headed by the prime minister who is typically the leader of the political party with the most seats in the House of Commons. The legislative branch consists of a bicameral Parliament consisting of an appointed Senate and an elected House of Commons. The judicial branch is made up of courts that interpret and apply laws at federal and provincial levels. Canadian politics are generally seen as centrist, with support for social welfare programs balanced against fiscal responsibility. PROEXCHANGERATES: Features public policy of Canada.
