What Gabriel Mackinnon does

Gabriel Mackinnon Lighting Design (GMLD) is an Ottawa-based, privately held architectural lighting design studio founded in 1974 by Philip Gabriel and now led by principal Andrew Mackinnon. The firm provides professional lighting design services across the full project lifecycle — concept, design development, construction documentation, and final installation and aiming — for institutional, government, retail, museum, hospitality, and high-end residential clients across Canada, with one major US commission (the 3 million sq ft American Dream shopping centre in New Jersey).

The firm's core technical capabilities center on custom fixture design and prototype development, heritage lighting rehabilitation (with mounting systems approved by FHBRO, NCC, and ACPDR), broadcast and theatrical lighting for parliamentary chambers (Senate of Canada, Supreme Court of Canada), museum-grade gallery and exhibit lighting using DMX-controlled and tunable-white LED systems, and LED retrofit specification that preserves original color temperature, CRI, and light output. GMLD develops bespoke luminaires in collaboration with Canadian manufacturers (Lumid, Nelson & Garrett, Lambert et Fils) and conducts lighting research with the National Research Council Canada. Notable technical assets include LEED Gold-certified projects, dark-sky-compliant fixtures, and heritage-compatible reversible mounting methods.

GMLD earns revenue through project-based professional service fees charged to enterprise property developers (Cadillac Fairview, Oxford Properties, Triple 5, Brookfield), federal and municipal government (Senate of Canada, House of Commons, Bank of Canada, City of Ottawa, NCC), cultural institutions (Canadian Museum of History, Royal Alberta Museum, Ottawa Art Gallery, Canadian Museum of Nature), national retail accounts (Metro Inc., with standards deployed across 100+ Ontario grocery stores), and hospitality operators. The firm operates on a relationship-driven, sales-led go-to-market in which Andrew Mackinnon's industry leadership in IALD and IES, repeat engagements over decades, and word-of-mouth through an established Canadian architectural partner network (Moriyama & Teshima, Diamond Schmitt, DIALOG, Perkins&Will, Reich & Petch, EVOQ) drive new business. The firm holds no patents, sells no products directly, and has no external investors.

Revenue model

1. Professional Lighting Design Services: GMLD generates revenue by providing comprehensive architectural lighting design services on a project-by-project basis. Engagements range from full lighting design for new construction and major renovations (e.g., American Dream at 3M sf, Parliament buildings) to specific scope items such as heritage building facade lighting, exhibit lighting, or retail lighting standards development. Revenue is earned through professional service fees, typically as part of a broader architectural or development project team. The firm also develops custom fixture specifications and performance requirements that are procured by clients, adding a product specification revenue component without manufacturing or selling fixtures directly.
