Since the 19th century, the main way to pay for electricity in most parts of Canada has been to regularly receive paper bills and then mail a check for payment. This traditional payment method is still in use today. The limitations of time and space not only bring a lot of inconvenience to people’s lives but also cause the country to waste a lot of unnecessary manpower and material resources. Meanwhile, since the use of this traditional payment method restricts residents from tracking the price and power consumption of the electricity meter, it is difficult to form electricity-saving habits and awareness. In the long run, this will also have a continuous negative impact on the country's environmental protection and sustainable energy development. Therefore, the entire market has a great demand for energy consumption and management services, and the government is also promoting the concept of energy saving. With the development of digital technology, Canada's power system is constantly innovating. However, Ontario still does not have a specific digital solution to help residents with energy monitoring and mobile payment.
