> I would argue that the use of this Act has already weakened democracy in Canada because it shows that the only response the political systems has to a very minor disruption is to use acts that everyone understood to be for much more extreme situations.

Certainly the act was used in response to weaknesses in the system - eg the Ottawa Police Service were unwilling to fine/ticket/otherwise deal with the illegal activity for weeks; crowdfunding sites weren't subject to FINTRAC; etc. Ideally this will lead to proper legislation regarding these weaknesses, removing the necessity of using the Emergencies Act to deal with a similar situation again.
