Parks and Public Spaces Alberta 3 Minutes Read · published February 11, 2026 Flag of Alberta

Calgary, Alberta maintains rules and operating practices for pruning trees in the public realm and on private property where municipal interests apply. This guide explains who enforces tree work, when seasonal pruning is recommended, when a permit or approval may be needed, and how to report hazards or request city pruning. It is written for homeowners, contractors and property managers working in Calgary’s urban forest and links to the city’s official guidance and permit pages for the most current requirements.

Contact the city before removing or majorly pruning trees on public land.

When to Prune

Pruning windows vary by objective. For general health and structure, late dormant season or early spring is common; for hazard reduction, immediate action may be required. Avoid heavy pruning during the growing season unless addressing urgent safety risks. For city-owned trees or work affecting sightlines, utilities or sidewalks, coordinate with Urban Forestry and follow the city guidance on approved timing and methods Calgary Urban Forestry – pruning guidance[1].

Types of Work and Permits

  • Routine crown cleaning and minor pruning on private property - usually no city permit required unless affecting protected or city-owned trees.
  • Pruning, removal or root work on boulevard or park trees - requires city approval or an application through Urban Forestry.
