An extraordinary day on Parliament Hill, for all the wrong reasons. MPs catcalled and shouted insults. Two were ordered out of the House – including opposition leader Pierre Poilievre. Plus: Pro-palestinian encampments at universities in Montreal and Vancouver show no signs of quieting. McGill asks for police help and a pair of students file for an injunction against the protestors. Also: As the United States struggles to contain a bird flu outbreak in dairy cows, scientists in Canada urge officials to get ahead of the virus now.
