Seligman first worked in the neighbourhood community of Lachine and later moved his bakery to the lane next door to Schwartz's Delicatessen on Boulevard St. Laurent in central Montreal.
Seligman would string his bagels into dozens and patrol Jewish Main purveying his wares, originally with a pushcart, then a horse and wagon and still later from a converted taxi.
Catering to this population, Montreal-style bagel shops have opened in Dartmouth, Nova Scotia, Vancouver, Ottawa, Toronto, Hamilton,[7] Calgary, Winnipeg, Whitehorse, and other Canadian, cities.
They have even spread to the UK and some US cities, such as Burlington, Houston, Los Angeles, Oakland, Portland[citation needed], and Seattle.
Gregory Chamitoff, who grew up in Montreal, took three bags of sesame bagels with him on his assignments to STS-124 as passenger and ISS Expedition 17 as crewmember.
