The process of initiating a telephone call to Canada from the United States involves understanding international dialing protocols. This requires knowledge of the exit code for the United States, the country code for Canada, and the specific area code and phone number of the intended recipient. For instance, to reach a number in Toronto, one would dial 011 (US exit code), followed by 1 (Canada country code), then 416 (Toronto area code), and finally the seven-digit local number.
Facilitating communication between individuals and businesses in these two countries is crucial for maintaining strong economic and social ties. Historically, reliance on landlines made international calls expensive and complex. The advent of VoIP technology and mobile communication plans has significantly reduced costs and simplified the calling procedure, making it easier to connect with contacts north of the border.
