Most internet service providers in Canada include the cost of renting the router or modem in your monthly service fee. However, you can buy a router outright from smaller service providers. Some providers also offer the rent-to-own option which enables you to save money especially if you plan to use the internet services long term. Buying your router gives you the option of more customization features in the future. Most individuals buy the router so that they can avoid connection slowdowns from ISPs and have more control over the network.
