Built on Reputation
Masonry Supplies
From concrete block and brick to specialty masonry units, Grand Valley carries the masonry materials Toronto contractors rely on for structural and decorative applications.
Natural Stone
Premium natural stone sourced from leading suppliers including Polycor, Banas Stone, and STONEArch. Ideal for custom facades, landscaping, and interior detailing across Toronto projects.
Landscape & Hardscape Supplies
Natural and decorative stone for Toronto outdoor projects — from patio pavers and retaining walls to garden edging and decorative aggregates. Grand Valley carries landscape hardscape lines from Unilock, Techo-Bloc, Rinox Hardscape, Bestway Stone, and Muskoka Rock.
Contracting Supplies & Accessories
Support your entire build with our accessories range — anchors, fasteners, sealants, joint products, and specialty contracting supplies for Toronto trade professionals.
Stone Lines & Collections
Explore curated stone collections in dozens of finishes — from smooth and polished to flamed, sandblasted, and tumbled — for architectural, landscape, and interior projects.
Thin Veneer Stone
Real stone, engineered for lighter loads. Grand Valley's thin veneer collection lets Toronto contractors and builders achieve a full natural stone look on facades, feature walls, and interior applications — without the structural requirements of full-thickness stone.
