Safety isn't a feature.It's the structure.
Every tube, tag, and toolbox talk exists so the crews, trades, and public under our structures go home unremarkably, every single day.
The audit is booked.
The habits came first.
Mammoth is pursuing COR (Certificate of Recognition), the national standard for occupational health and safety management systems, audited independently and recognized by Ontario's largest owners and general contractors. We're building the documentation, training records, and internal audit culture now, because the standard was never the point. The crews going home safe is.
What COR means for your project
- Independently audited health & safety management system
- Pre-qualification recognized by major GCs and public owners
- Documented training, inspections & incident protocols
- Annual maintenance audits, not a one-time badge
Target: certified 2026 · status updates on request
Two locals. One standard.

Toronto & GTA
Trained, ticketed journeypersons and apprentices with working-at-heights, and trade-specific scaffold certification through the union training centre.

Hamilton–Niagara
Southern Ontario coverage with the same training standard, so a Niagara install gets the same crew quality as a downtown Toronto tower.
Boring on purpose.
The most exciting thing that should ever happen on a Mammoth structure is the view. Here's the routine that keeps it that way.
Site-specific safety plans
Every project gets its own hazard assessment and safety plan before mobilization, not a photocopied binder.
Engineered drawings & load ratings
Where the scope calls for it, structures go up from stamped erection drawings with posted load ratings.
Scheduled inspections & tagging
Green-tagged at handover, re-inspected on schedule and after weather events, with records you can show your consultant.
Certified working-at-heights crews
Union-trained scaffolders with current working-at-heights and trade certifications, verified before they reach your gate.
WSIB coverage & insurance
WSIB clearance and liability coverage available for your pre-qualification package on request.
Daily hazard talks
Toolbox talks and daily hazard assessments: the five minutes that keep the other eight hours boring.
WSIB clearance & certificates of insurance available for pre-qualification packages on request.
Inspected on a schedule, not on a hunch.
- 01
Site walk & drawings
We walk the site before we price it. Access, loading, public interface, and sequencing get sorted on paper first, so the quote you get is the quote you pay.
- 02
Engineering & planning
Erection drawings, load ratings, and permits where the scope calls for them. The plan covers the dismantle before the first standard goes up.
- 03
Erect & certify
Union crews build it clean, on schedule, and tag it for handover. Inspected, documented, ready for your trades.
- 04
Support through completion
Adaptations as your project moves, scheduled inspections while it stands, and a dismantle that leaves the site like we were never there.
Need the paperwork?
We like that about you.
Safety plans, drawings, insurance, WSIB. Ask for the package. Contractors who check are contractors we like working under.
