Deeply wish the Canadian government would do the same. Blind support-at-all-costs does nothing to further peace. I think the Hamas attack was reprehensible, but Hamas does not speak for all Palestinians, just like Israel does not speak for all Jews.
Israel is engaged in collective punishment at best (a war crime) or genocide at worst (a war crime). A negotiated settlement is clearly not viable given remarks by the Israeli government.
I am Jewish. My family is Jewish. My grandparents survived concentration camps and genocide. Despite their experiences, they lived lives of compassion. They would abhor the actions of the Israeli government - as do the rest of my family. Criticism of Israel is not antisemitism. It is criticism of a government.
