Then arrest the people who are breaking the laws and blockading critical infrastructure, and charge them with a criminal offence. The BLM protests also saw many criminal elements that did looting and assaults. None of this is a valid argument for freezing accounts of people "involved" without due process.
The Emergencies Act is specifically for when there is an urgent and critical public order emergency. It's invocation is going to be ratified by the Parlaiment today. The police unfortunately dropped the ball, they tried that option too. But just arresting specific people also wasn't enough. Polling shows that the majority of Canadians supported the use of the act.

3. FLQ Crisis - an incident that included the kidnapping of federal ministers by a terrorist organization
By contrast, this protest has been incredibly peaceful when compared to other similar protests or occupations. There is a debate happening in parliament right now on whether or not to extend the Emergency powers now that the government has successfully cleared the protestors and taken back control of downtown Ottawa.
I personally don't believe this incident warranted the suspension of civil liberties. It isn't clear to me that the government did what they could to apply the existing laws on the books. If anything the biggest issue was that the Ottawa police appeared reluctant to enforce existing laws on the protestors. That is a different issue and does not justify the imposition of the Emergency act.
