G3 Media

G3 Media is a Quebec-based out-of-home media company and a major independent player in billboard advertising across eastern Canada. The company owns and operates a network of more than 667 traditional and digital billboards concentrated in five key markets: Greater Montreal, Greater Toronto, Quebec City, Trois-Rivieres, and Sherbrooke. Its inventory spans a wide range of formats, including digital posters, backlit panels, large-format digital boards measuring up to 16 by 56 feet, static superboards, and both vertical and horizontal poster displays, giving advertisers flexibility in size, location, and creative approach.

G3 positions itself as an innovation-focused operator committed to redefining the standards of outdoor advertising, delivering high-impact campaigns driven by creativity, data, and technology. For its digital inventory, the company offers programmatic access through demand-side platforms, allowing brands and agencies to integrate G3's screens into broader omnichannel and data-driven media strategies. Having rapidly assembled its portfolio through acquisitions in Quebec and Ontario, G3 has become one of the largest OOH players in the Canadian market, competing with national incumbents while maintaining an independent, entrepreneurial identity.

The company handles strategic placement, marketing, and campaign execution, working with advertisers to match messaging to high-traffic locations in and around major metropolitan centers. By owning its billboard structures and combining static and digital formats with programmatic capabilities, G3 Media operates as a full-fledged media owner. Its concentration in Quebec and Ontario's busiest urban corridors makes it a significant regional force in Canadian out-of-home advertising.
