That's fairly typical. Most municipal emergency powers are limited to what would typically fall within the jurisdiction of the municipality.
Where you really see the most teeth, all across the emergency legislation, is with the provinces. The provinces' emergency powers are by far the beefiest, compared to the municipalities and to the federal government, and that makes sense, because the tools to respond to what we think of as a typical emergency rest with the provinces. For example, policing, health services and emergency services are held at the provincial level.
