Calgary Bylaws: Contractor Tree Care Standards

Parks and Public Spaces Alberta 4 Minutes Read · published February 11, 2026 Flag of Alberta

In Calgary, Alberta, contractors who work on public- and city-owned trees must follow municipal standards, procurement rules and permit requirements to protect urban canopy and public safety. This guide summarizes city controls, procurement practices for contractors, enforcement pathways and practical steps to obtain permits, bid on work, perform accepted arboricultural care and report concerns. Where official pages provide details we cite them directly; where specific fines or forms are not published on the cited page we note that explicitly to help contractors and procuring authorities plan compliance.

Standards for Contractor Tree Care

City of Calgary Urban Forestry and Parks set operational standards for pruning, removal, planting, staking and protection of trees on city property and in parks. Contractors working under city contracts must hold appropriate certifications, follow accepted arboricultural practices, and meet insurance and workplace-safety requirements. See the city’s urban forestry guidance for scope and municipal expectations: City of Calgary Urban Forestry[1].

  • Documentation: Maintain written work plans, site protection drawings and tree-condition records.
  • Qualifications: On-site certified arborist supervision where required.
  • Methods: Use accepted pruning cuts, climbing and rigging protocols to avoid bark and root damage.
  • Protection: Install temporary fencing and root protection for construction near trees.
Contractors should document tree protection measures before work begins.

Procurement & Contracting

City procurement processes require vendors to register, meet insurance limits, and respond to public bid opportunities or request-for-proposal processes for parks and urban forestry contracts. Public procurement pages describe current bid opportunities and supplier requirements: City of Calgary Procurement & Bid Opportunities[2].

  • Prequalification: Some programs use vendor prequalification lists for tree care contractors.
  • Insurance and bonding: Meet city-specified minimums before award.
  • Bid submission: Observe stated deadlines and submission format in each solicitation.
  • Vendor support: Contact procurement officers for clarification on scope and evaluation.

Penalties & Enforcement

Enforcement of tree care, damage and unauthorized removals on city property is handled by the City of Calgary departments responsible for parks and bylaw enforcement. The city’s enforcement pages describe complaint pathways and enforcement roles: Bylaw Enforcement and Compliance[3]. Specific monetary penalties, escalation ranges and appeal timelines are not specified on the cited page.

  • Fine amounts: not specified on the cited page.
  • Escalation: information on first, repeat or continuing offence penalties is not specified on the cited page.
  • Non-monetary sanctions: orders to remediate, stop-work orders and restoration requirements are used; exact remedies are described on enforcement pages.
  • Enforcer: Bylaw Enforcement and Parks/Urban Forestry are responsible for inspections and enforcement; use the city complaint and contact pages to report damage.
If you observe suspected unlawful tree damage on city land report it promptly using official channels.
