An all-in-one (AIO) product is a financial product that combines multiple banking and investment services into a single account. In Ontario, AIO products are typically offered by banks and other financial institutions as a way for customers to manage their money more efficiently and conveniently.

AIO products may include a checking account, a savings account, and a line of credit, as well as other services such as credit card, mortgage, and investment services. Customers can access these services through a single account and may be able to take advantage of features such as lower fees and higher interest rates on their savings.

AIO products can be a convenient and cost-effective option for individuals who want to manage their finances in one place, but it's important for customers to carefully consider the terms and conditions of the product before committing to one.
