Transcontinental Inc., operating as TC Transcontinental, is a Montreal-based retail marketing services provider, as well as a commercial printing and specialty media company.

Transcontinental is publicly-traded on the Toronto Stock Exchange, and has over 4,000 employees—the majority of which are based in Canada.

The company was founded in 1976 by Rémi Marcoux and partners Claude Dubois and André Kingsley as a flyer-printing business. It generated $2.9 million in revenue in its first year of operations. In 1978, the company was renamed GTC Transcontinental Group Ltd., and it established a Door-to-door flyer distribution division known as Publi-Home Distributors.

In 1979, the company entered the publishing industry after acquiring Les Affaires and SIC. It also purchased the Imprimerie Chartier (now Transcontinental Saint-Hyacinthe) printing plant. In 1984, the company went public on the Montreal Exchange, and later the Toronto Stock Exchange. Transcontinental subsequently performed a number of acquisitions over the decade that followed, including 20 Telemedia-owned community newspapers in the Montreal area, The Hockey News, and a number of commercial printing companies (including Southam Inc.'s plants and printing division), among others.

On January 29, 2000, GTC Transcontinental announced its acquisition of the publishing business of Telemedia for $150 million, including Canadian Living, Homemakers, and the Canadian editions of Elle and TV Guide. In 2002, Transcontinental acquired 12 newspapers and two printing plants in Atlantic Canada and Saskatchewan from CanWest Global for $255 million, in what was one of the company's largest transactions to date.

In 2003, after receiving the contract to print La Presse, the company established its new Transcontinental Métropolitain printing plant. In 2006, the company enters a segment offering strong growth potential in the publishing market by acquiring Chenelière Éducation, the leading publisher of French-language educational resources in Canada. In 2011, Transcontinental reached an agreement to exchange assets with the U.S. printer Quad/Graphics, acquiring six of its Canadian plants (dating back to its predecessor Quebecor World) and a prepress in Markham, Ontario, in exchange for Transcontinental's Mexican operations, and a stake in a black-and-white book printing operation owned by the company.

In 2012, Rémi Marcoux stepped down as chair of the board, and was succeeded by his daughter Isabelle Marcoux. In December 2013, Quebecor Media subsidiary Sun Media announced that it would sell 74 of its community newspapers in Quebec to Transcontinental in a deal valued at $75 million. The Competition Bureau approved the sale in May 2014, under the condition that Transcontinental divest 34 of its Quebec newspapers for competition reasons. In March 2014, Transcontinental acquired U.S.-based Capri Packaging to expand into the flexible packaging market. The company described it as a "new promising growth area", amidst softening revenue in advertising, and decreases in its core printing businesses. In November 2014, Transcontinental sold 15 of its consumer magazines, including Canadian Living and The Hockey News, to Quebecor's Groupe TVA for $55.5 million. Transcontinental also received a contract to print magazines and marketing materials for TVA through 2021.

In May 2016, Transcontinental sold its 13 newspapers in Saskatchewan to Star News Publishing of Alberta. As a result, a Transcontinental plant in Saskatoon was also shut down. On December 1, 2016, Transcontinental Media acquired Rogers Media's financial industry publications, including Advisor's Edge, Avantages, Benefits Canada, and Conseiller.
