No. An IRS is a provincial administrative penalty and does not, by itself, result in a criminal conviction or criminal record. However, it still carries serious consequences, including an immediate licence suspension, vehicle seizure, a financial penalty and possible participation in an ignition-interlock program.
A conviction for an impaired-driving offence under the Criminal Code is different. It results in a criminal record and may also involve a court-imposed driving prohibition, a fine and, in more serious cases, imprisonment.
