The central issue with invoking the Emergency Act is twofold: First, it is a step too far in consolidating state power against dissenting citizens. Second, police already had the tools they needed to deal with the occupation in Ottawa but chose not to. If the police had exhausted all their options first (which are routinely used against Indigenous and climate change protestors) then Trudeau may have a case. This did not happen.
The organizers of the covid convoy have been demanding they speak to the manager of Canada. While they claim to fight for freedom and "vaccine choice," this couldn't be further from the truth. What all the elements within the spectrum of supporters of the convoy have in common is the promotion of social harm.
Justin Trudeau has chosen to place all of the blame on the unvaccinated for the current spike in cases and hospitalizations. The problem is, this is only a half-truth. It is political scapegoating. The other half of the problem is Trudeau himself - and the rest of Canada's political elites who have declined to improve Canada's public health system for decades. There is so much more that our political leaders could have done to prevent, or at least mitigate, the current surge in Omicron cases and hospitalizations.
The internal logic of capitalism has tainted our government's response to the pandemic. Corporate profits were preserved, while the interests of the working class were disregarded. Pandemic austerity and vaccine nationalism were the primary themes of government responses, and have grave consequences for the working class and health of humanity. An alternative solution, worker-ownership, is good public health policy as it would empower workers to create their own safe pandemic working conditions.
