Mr. Sub, originally called Mr. Submarine before the 1990s, is a submarine sandwich store chain in Canada. The first store was opened in 1968 in Toronto's Yorkville neighbourhood which was then known for its hippie culture. There are now over 450 restaurants all across Canada. Mr. Sub only exists with two locations in Quebec (with only Montreal and Gatineau locations), since in Montreal, it is now mutually exclusive with the ToastySub chain.
The franchise is owned by Mr. Submarine Limited. Its headquarters, formerly on Spadina Avenue, is currently located on Yonge Street in Toronto, Ontario. The original owners of Mr. Submarine, now known as Mr. Sub, were Jack Levinson and Earl Linzon. Later, some of the shares of the company were given to Levinson's brother, Bernard. Mr. Submarine did not become a major concern, however, until Gus Boulis, a Greek immigrant (see Gus Boulis) was hired as dishwasher. It was Gus Boulis who showed Levinson and Linzon how to franchise. Boulis was soon offered control of one of the stores, and shares in the corporation. Boulis knew that he was working too hard to make Levinson and Linzon rich. Levinson was a partier and Linzon a gambler. When Boulis announced that he wanted to sell his shares, Levinson was so afraid that he would lose everything, he suffered a nervous breakdown. In his five years with the company Boulis developed a chain of over 200 stores. The sale of the Boulis's shares in the company in the mid-1970s, back to the original owners, made Boulis a multimillionaire, and he was only 25 years old. Levinson recovered from his breakdown when he learned that he had more money, as a result of Boulis's hard work and entrepreneurial savvy, than he had ever anticipated having. Levinson and Linzon continue to own Mr. Sub.
Mr. Sub's slogans were Lub my Sub, then Fresh thinking is what we are, "Taste a Canadian Tradition", " It's not a sandwich it's a Sub", followed by There's always something good going down at Mr. Sub, and finally, More Than Enough, its present slogan.
Mr. Sub is not on sale according to its co-founder, however there was speculation in 2005 that Michael Bregman, the former owner of the Second Cup coffee chain, was contemplating a purchase of the chain. Other names floated as possible suitors have included Swiss Chalet parent Cara Operations and KFC operator Priszm Canadian Income Fund. The donut chain Country Style was briefly interested in Mr. Sub in 2005.
