I'm not an expert in Canadian law, but are there any elected officials in the chain of the decision to conduct a raid? If so this ought to be severely career limiting. If it was an elected judge who approved the warrant, for example.
But if it is anything like here in Australia (we are both Westminster systems) then this does not mean the government is held accountable. Judge appointments are assumed to be fairly neutral and it hardly ever comes up at election time.
