GCN Constructors Inc. (GCN) was incorporated March 21, 2018, to provide Construction Management and General Contracting services to commercial, industrial, and institutional clients.

After 15 years of professional construction management, including the last 2-years as President of one of Ottawa’s oldest general contractors, GCN’s founder, Josh Hornung, established GCN Constructors.

Mr. Hornung is a Professional Engineer,past Director and Secretary of the Board of the General Contractors Association of Ottawa and is highly regarded among his peers.

He is well known and respected in the Ottawa construction industry for his successes, construction knowledge, and commitment to his clients.

All GCN’s projects are overseen by Mr. Hornung.



Truly successful construction projects result when a strong team of experienced and accomplished construction leaders assemble to represent and protect the Owner’s interests throughout the project's con.

Construction Management

Similar to how an Architect is the consultant for the Owner for design, the Construction Manager is the consultant for the Owner on construction when the Owner chooses to perform the building construction as the General Contractor 

When brought into the project early, during design and the Pre-Construction, GCN will advise on design-constructability, materials, products, specifications, and how they relate to the optimum solution for the Owner in costs, quality, and duration of the construction.

General Contracting

When the Owner does not want the responsibility or risk associated with taking on the construction themselves, GCN will perform the work as the General Contractor under either lump-sum or Cost-plus contract.

GCN remains fully committed to the Owner's interests and successful performance of the project, underwritten by our insurance and bonding facilities, the project is safe-guarded from every angle.
