TORONTO — July 1 is Canada’s 150th anniversary, but nobody seems particularly eager to join the party. The muted attempts at celebration have so far produced either awkwardness or embarrassment. A giant rubber duck, six stories tall, is supposed to arrive in Toronto Harbor on Canada Day, but its imminent appearance has been greeted by outrage over costs and suspicions of plagiarism. In March, the CBC, Canada’s national broadcaster, began televising a documentary series called “The Story of Us” to the almost instantaneous howling of Quebec and Nova Scotia politicians at what they regarded as significant omissions in our supposedly collective narrative. Resistance 150, an indigenous political movement, is planning to disrupt the anniversary itself.

The principal excitement of our sesquicentennial so far has been the fury of national self-critique it has inspired.

The irony is that Canada, at the moment, has a lot to celebrate. Our prime minister is glamorous and internationally recognized as a celebrity of progressive politics. We are among the last societies in the West not totally consumed by loathing of others. Canada leads the Group of 7 countries in economic growth. Our cultural power is real: Drake recently had 24 songs on the Billboard Hot 100 at the same time — for one shining moment he was nearly a quarter of popular music. Frankly, it’s not going to get much better than this for little old Canada.

So why is Canada so bad at celebrating itself? The nationalism that defined the country during the last major anniversary, the centenary in 1967, has evaporated. The election of Justin Trudeau has brought a new generation to power, a generation raised on a vision of history more critical than laudatory. We dream of reconciliation with the victims of our ancestors’ crimes rather than memorialization of their triumphs.
