There is the explicit antisemitism — the masked and keffiyeh-clad protesters propping up terrorism, the street tags, the social posts, the violence. It can be photographed, prosecuted, condemned in a press release. And then there is what I call the greatest threat: subversive antisemitism. It wears institutional clothing — and it is far more dangerous precisely because it is deniable. It sits inside the Canada Revenue Agency, stripping century-old Jewish charities of their status without due process, while organizations with documented ties to terror-designated groups collect Canadian taxpayer money undisturbed. It sits on school boards that bus students to anti-Israel rallies as though they were field trips. It sits in our public broadcaster, framing Israeli self-defence in language so distorted audiences can no longer distinguish between a military response and a massacre. It sat on the government committee struck to study antisemitism — appointed there by the prime minister himself — individuals with documented terrorist sympathizers. It wore a lapel pin reading “From the River to the Sea” while serving passengers on an Air Canada flight at 35,000 feet. It pencilled hate slogans into the sidewalks of Collingwood, Ont. There are too many incidents of betrayal, making Jews feel unwelcome and unsafe — too much of a licence granted to the haters to act without consequence. And yet each hostile event gets explained away. An aberration. An isolated case. But these are not isolated. They are a pattern sustained across institutions, over years, with impunity. It is a policy of permission — one that normalizes antisemitism with a distinct message: Jews not welcome in Canada.
