By 1967, Jim Pattison had acquired all the shares of Neon Products/Seaboard and turned the public company into a private holding.

The company was a major supplier of store identification, display, vehicle and gold leaf signage in the early days of Edmonton.

Merging in 1992 with Pillar Ad, another Pattison acquisition, Gould moved beyond its established markets in southwestern Ontario and embarked on a rapid expansion program in the Greater Toronto Area.

The transit advertising component of Pattison Outdoor is rooted in Trans Ad, a Canadian company founded in 1912.

In March 2011, Pattison Outdoor Advertising acquired Onestop Media Group (Onestop), designers and operators of digital advertising networks for the transportation, malls, sports retail, residential and hospitality industries.

[3][4] Pattison Outdoor currently holds transit advertising contracts with twenty-one municipal transit authorities, and a number of third parties which give Pattison access to sell into an additional thirteen markets, including Quebec, and Saskatchewan.

In terms of place-based advertising, Pattison has contracts with the property owners and managers of over 300 commercial shopping centres across Canada, as well as operating digital advertising networks in office towers, retail stores, residential buildings, hotels and transit stations platforms.

Pattison Outdoor Advertising's inventory includes the following out of home media: In 2011, Pattison Outdoor Advertising disallowed Beyond Coal, who had bought billboard space on one of the company's billboards, from displaying an anti-coal message until references to the nearby Westshore Terminal, where 700 train cars of coal are loaded each day, were removed.

[5] In 2012, Greenpeace was engaged in talks with Pattison Outdoor Advertising to display a billboard advocating renewable energy sources, but the company abruptly terminated the discussions.
