Even though the Ministry refunded the cost of licence plate stickers, there is still a requirement to renew your licence plates before your birthday. Here is the link to the Service Ontario page where you can renew your plates online.

Your vehicle must have a valid licence plate and be insured to drive legally in Ontario. The licence plate renewal period varies depending on the type of vehicle and if you choose to renew for one or two years.
