Hardscaping & Interlock

No provincial trade licence required

Hardscapers build the hard parts of landscapes — interlock driveways and patios, retaining walls, steps, and outdoor living spaces. It is where landscaping's margin lives: high tickets, portfolio-driven sales, and craftsmanship that fails publicly if the base prep is wrong.

The licensing layer, explained

No trade licence. Business licence, WSIB, and insurance apply; Ontario One Call locates are required before excavation, and structural retaining walls (typically over ~1m) can require engineering and permits. ICPI (interlock) and SRW (segmental retaining wall) certifications are the industry credentials that signal proper base and drainage practice.
