Kevin Wiener, a 20-year-old student at the University of Western Ontario, has filed an application with the Ontario Superior Court of Justice to challenge anti-drunk-driving legislation that he says discriminates based on age. The new legislation requires Ontarians under 22 years old to have no alcohol in their blood while driving. The law is in addition to laws already on the books that punish drivers of all ages whose roadside blood-alcohol content is above 0.05. Wiener says the rules, which allow for 24-hour roadside suspensions, plus fines of up to $500 and 30-day suspensions, violate the Canadian Carter of Rights and Freedoms, which protects against age discrimination. Ontario’s Transportation Minister Kathleen Wynne said the law is necessary because drivers aged 19-21 who are involved in crashes are 1.5 times more likely to have some level of alcohol in their blood.
