Canada

I think you misunderstand what "exceptionalize" means in this use. Exceptionalizing means that something is defined as deviant with either a positive or negative connotation, or in other words, that its traits are constructed as exclusive to it rather than as typical of whatever group that the exceptioanlized thing belongs to.

To exceptionalize Zionism as a hate-group would be to say that it is unusual in its motivations and tactics compared to settler-colonial states and politics generally as well as other hate groups. Zionism in Canada is very much enacting genocide in its moblization of sympathetic groups within Canada and influence on the investment and funding policies of institutions within Canada as well as the Canadian state; which again, directly supports Israel's genocide of Palestinians. I'm not saying that Zionism should not be classified as a hate group or discussed as a hate group, since its subscribers do have specific political intentions and interests, but that we cannot exceptionalize the racist, genocidal politics of Zionists as anomalous or deviant from Canadian politics or from white supremacy. There is a misconception that Israel is somehow hyperbolic in its violence, even though its methods and effects are comparable to that of the US and Canada, and any white supremacist groups within them. Canada is a white supremacist state, despite incidental and periodic protections for racialized peoples, but considers overtly white supremacist groups as hate groups as it allows the state to define white supremacy by the image of those hate groups, not its underlying philosophy and historical processes.

The reason Canadians are only willing to recognize Zionism as genocidal once its violence became undeniable during the most documented genocidal campaign in human history is exactly because that immorality is now obvious in the same way that white supremacist militias within Canada and the US are obviously immoral. The overtness of that violence allows the liberal state to construct its softer, more gradual tactics as something completely distinct from genocide or racism. A great example of why this is so important is the fact that Hamas is already defined as a terrorist group in the Criminal Code, which was recently amended through Bill C-9 to define hate as, "as an emotion of an intense and extreme nature that is clearly associated with vilification and detestation." Therefore, any equivalency between these "hate groups" would mean that the politics of Zionists and Palestinian resistance are equivalent, "both sides are bad because they are exceptionally violent and express hatred for another group," which hardly describes the power differential between those groups as well as the sympathy that the Canadian state has for only one of those groups and why.

Hope that explains it better.
