Ontario Construction Association Alliance

What Ontario Construction Association Alliance does

Ontario Construction Association Alliance operates Link2Build, a digital tendering and construction-trade-news platform founded in 2018–2019 as a partnership of seven Ontario construction associations: Grand Valley, Kingston, London & District, Niagara, Northeastern Ontario (NOCA), Ottawa, and Windsor Construction Associations. The platform serves as Ontario's largest construction project information conduit, connecting construction purchasers (public and private sector) with contractors across six geographic zones spanning the province. It represents more than 4,000 member companies including general contractors, consultants, subcontractors, heavy construction companies, suppliers, and professional services organizations, and hosts nearly 10,000 to over 12,000 construction bid opportunities annually.

The core technology is a proprietary electronic plansroom and bidding platform (tenders.link2build.ca) built and maintained by eSolutionsGroup Ltd. under a 20+ year technology partnership. Adjacent products include a Certificate Publishing Service for Ontario Construction Act notices (Section 32) at a flat $199 per notice, a public Construction Directory (publicdirectory.esolg.ca), a Link2Build Daily News Brief for the ICI construction sector, and pre-paid certificate packages for high-volume publishers. The platform is recognized as satisfying the statutory definition of a construction trade newspaper in electronic format.

Revenue is generated through three streams: subscriptions (province-wide access at $3,999 annually, plus zone add-ons at $600 per zone for association members), transaction fees for Construction Act certificate publishing ($199 per notice, pay-as-you-go), and website advertising targeted at construction suppliers and service providers. The organization is structured as a non-profit partnership, is 100% Canadian owned and operated, and distributes services both through the seven association memberships and direct province-wide digital subscription.

Scale indicators5 records

Recent moves5 records

Expansion highlights4 records

Broad incumbents

• MERX: MERX is the dominant Canadian public-sector e-tendering platform, aggregating opportunities from federal, provincial, and municipal governments. It overlaps with Link2Build's public-sector tendering offering but operates at broader national scope and across multiple procurement categories beyond construction.
• ConstructConnect: ConstructConnect (which includes iSqFt, Dodge, and CMD) is a leading North American construction bid aggregation and project intelligence platform. While broader and more data-focused than Link2Build, it competes for the same contractor subscriber base seeking construction project leads.
• BuildingConnected (Autodesk): BuildingConnected, part of Autodesk Construction Cloud, is a bid management and subcontractor network used widely in North America. It targets the same general contractors and subcontractors that Link2Build serves, though with a stronger emphasis on workflow software than on statutory notice publishing.
• Canadian Construction Association: The Canadian Construction Association is the national umbrella body for Canada's construction industry, providing advocacy, standards, and member services. It operates one level above Link2Build and represents the broader industry context in which Link2Build functions.

Regional players

• Toronto Construction Association: The Toronto Construction Association is one of the largest regional construction associations in Ontario (and notably not part of the Link2Build alliance). It provides member services and tender information to GTA-area contractors and represents a parallel, non-affiliated distribution channel competing for the same GTA contractor audience.
• Alberta Construction Association: The Alberta Construction Association is a provincial construction industry association analogous to the seven founding members of the Link2Build alliance. It represents the regional peer model that Link2Build would need to replicate to expand beyond Ontario.
• BC Construction Association: The BC Construction Association and its regional member associations (including the Vancouver Regional Construction Association) operate a model very similar to the seven Ontario associations behind Link2Build, providing member services and tender information in British Columbia.

Emerging players

• PlanHub: PlanHub is a digital preconstruction platform connecting general contractors with subcontractors through bid invitations and project leads. It competes with Link2Build's plansroom functionality for the same general contractor and subcontractor users, though without a comparable statutory notice publishing offering.

Direct peers

• bids&tenders: bids&tenders is a Canadian e-tendering platform operated by eSolutionsGroup—the same technology provider that powers Link2Build. It directly competes in the same construction tendering category, serving public and private purchasers with similar plansroom and bid management functionality.
• Biddingo: Biddingo is a Canadian e-procurement and tendering service that aggregates public and private bid opportunities, including construction tenders. It competes head-to-head with Link2Build for Ontario public-sector purchasers and contractor subscribers, offering similar plansroom functionality.
