Returning builders get priority and the same arborist

  • We find cash-in-lieu savings before you file

    Moving a protection fence two feet or adjusting a TPZ boundary can cut thousands in cash-in-lieu charges. We flag those before you file.

  • No re-explaining your process

    We keep your standards on file, so each new project starts without a briefing.

  • Priority scheduling

    Returning clients get first pick on site visits.

  • Same arborist, application support included

    One ISA Certified Arborist on all your projects, with city-specific application notes in every report.

Five permit rules that catch builders mid-project

  • Pickering

    Inside its designated Tree Protection Areas, protects trees at a small size. Confirm the protected size with Pickering. Outside those areas, no City permit applies.

  • Hamilton

    Hamilton has no single tree bylaw. Ancaster, Dundas and Stoney Creek keep old rules for specified trees or land only. Woodland, City tree, conservation, development and mapped rules apply on top, anywhere in the city.

  • Toronto

    The ravine bylaw protects trees of any size. A 5 cm sapling in a ravine zone gets the same protection as a 100 cm oak.

  • Richmond Hill

    Lowered the minimum diameter from 20 cm to 15 cm in 2025. Active Plan of Subdivision or Site Plan applications submit arborist-prepared preservation plans through planning and do not need a separate Tree Permit. Cash-in-lieu is $945 per required replacement tree.

  • Brampton

    Continuing offence penalty: up to $10,000 per day. Replanting requirements are at the Commissioner's sole discretion.
