Hiring Checklist for St. Catharines
Before hiring a tree service in St. Catharines, verify every item on this list. These steps protect your investment and ensure you are working with a qualified professional.
Verify the ISA Certified Arborist credential at isa-arbor.com using the certification number
Confirm a current WSIB clearance certificate and at least $2M general liability insurance
Check whether your tree needs a municipal removal permit — most Ontario cities protect mature trees
Get a written fixed-price quote specifying tree species, size, scope, debris cleanup, and stump handling

Confirm they own their climbing and rigging equipment rather than subcontracting to an unverified crew
Red Flags to Watch For
If a tree service in St. Catharines displays any of these warning signs, consider looking elsewhere. Protecting yourself starts with recognizing these patterns.
Knocks on your door after a storm offering immediate work
Cannot provide an ISA Certification number or proof of WSIB
Quotes verbally without inspecting the tree or your property

Questions to Ask Before Hiring
Do you have an ISA Certified Arborist on staff?
Good answer: Yes, my certification number is [number]. You can verify it at isa-arbor.com.
Do you carry WSIB and at least $2M liability insurance?
Good answer: Yes, I can provide a WSIB clearance certificate and a current insurance certificate before we start.
Does this tree need a permit, and will you handle it?
Good answer: I check the municipal bylaw first. If a permit is required, I prepare the arborist report and submit the application.
Is stump grinding included in this quote?
Good answer: I quote stump grinding as a separate line item so you can decide. Removal and grinding are not the same job.
