(Op-ed by Robert Leckey, Faculty of Law): It's a banner year for same-sex marriage. This June will mark 10 years since the first gay couples wed at Toronto city hall. Elected lawmakers are debating legislation on the subject in France and Britain. The U.S. Supreme Court will soon rule on it. After a decade in Canada, there's much to celebrate. But the anniversary also prompts reflection on analogous harms and injustices that equal access to marriage hasn't solved, and might even have made worse.
