Supermartifacts / The Artifacts of Steinberg

[Steinberg logo]

The Steinberg (or Steinberg's) supermarket chain was founded in Montréal by Ida Steinberg in 1917. By mid-century, Steinberg had emerged as the leading grocer in Quebec. The company also took part in an aggressive expansion to Ontario (expedited through the acquisition of Grand Union's Canadian operations), and was among the first chains to locate stores in modern shopping centres.

In 1969 Steinberg converted the bulk of its Ontario stores to a discount format and rebranded them as Miracle Food Mart, while maintaining the Steinberg brand in Quebec. Regardless of which brand it used, Steinberg had a reputation for innovation and expressive store architecture, and maintained it well into the 1970s.

Steinberg began to falter competitively in the 1980s, and its operations began to succumb to infighting among Steinberg family shareholders over business decisions. In 1990 the Miracle Food Mart division in Ontario was sold to A&P, who converted most of the stores to their own banner (and later still, Food Basics). The rest of the company was dismantled over the next two years, with Metro and Provigo taking over most Quebec locations in 1992. So endeth the tale of Steinberg.

Before Steinberg expanded into the interior of Ontario in 1959, a base of stores existed built by a preceding firm: Carroll's, based in Hamilton. Carroll's was acquired by Grand Union of New Jersey in 1953, with a brief period of co-branding following. Steinberg bought Grand Union's Canadian operations in 1959.

754 Dundas St., London, ON

Carroll's expanded from Hamilton to London, Ontario by 1935, and this building housed one of the four stores that represented its early presence in the city. None survived the 1940s, and Carroll's withdrew from the city until re-entering under Grand Union several years later.

1080 Adelaide St. N., London, ON

Opened as Carroll's-Grand Union circa 1955; converted to Steinberg in 1959 and Miracle Food Mart in 1969. Divested to the Oshawa Group in the 1980s, and later Price Chopper and Fresh Co. Expanded and remodelled severely.

[Grand Union/Steinberg store]

274 Highland Rd. W., Kitchener, ON

Opened as Carroll's-Grand Union circa 1955; converted to Steinberg in 1959. Steinberg then withdrew from Waterloo-Kitchener by 1965, divesting its stores to the Oshawa Group's Dutch Boy division. This store has continued to operate in the Oshawa/Sobeys fold ever since.


[Steinberg store]

351 Margaret Ave., Kitchener, ON

Opened as Steinberg circa 1960; however, it converted to Dutch Boy by 1965 and remained Dutch Boy through the 1990s. Dutch Boy may have also "blandified" the exterior of this store during its period of operation; Steinberg stores usually looked more exciting than this.

The Westown Shopping Plaza in London featured Steinberg's as an anchor when it opened in 1960. Successors to Steinberg (Miracle Food Mart, A&P, and Metro) have operated in the mall ever since. However, the present store is not the original store: A brand-new building was constructed for Miracle Food Mart when the plaza was enclosed in the 1970s or 1980s. The original store was subsumed into the mall's interior, and featured a zigzag roofline that is still visible in the central court.

[Food Basics store]

751 Upper James St., Hamilton, ON

Originally the site of a Steinberg store, opening during the first half of the 1960s. Later converted to the Miracle Food Mart, Ultra Mart, Metro, and Food Basics brands, assuming the lastmost identity by 2020.

Miracle Food Mart

1299 Oxford St. E., London, ON

Opened as Miracle Food Mart in the early 1970s; later A&P and Food Basics. This is a mall store with access only from the interior corridor. Note the unusual concrete exterior detailing, which is evocative of the brutalist aesthetic of the era...and was subsequently removed in a 2020 renovation.

1375 London Rd., Sarnia, ON

Opened as Miracle Food Mart in the early 1970s; later A&P, A&P Super Fresh, and Metro. I'm unsure how much of the facade is original: The box-like backing for the sign probably isn't, but the arches might be.

1491 Ernest Ave., London, ON

Opened as Miracle Food Mart circa 1980. Note the concrete wedges underneath the windows, similar in theme to the detailing of the Oxford St. store.

509 Commissioner's Rd. W., London, ON

This was the last new Miracle Food Mart location to open in London, hailing from the latter half of the 1980s. It features a stairstep facade and an unusual octagonal floorplan, reflecting both the site constraints and Steinberg's penchant for out-of-the-ordinary stores.


In the late 1980s, Steinberg began branding upsized Miracle Food Mart stores as "Ultra Mart." A&P elected to retain Ultra as a distinct brand following their 1990 purchase of Steinberg's Ontario division, even going so far as to expand the chain with new stores under their ownership. Ultra thus served as a coda to Steinberg's legacy in Ontario, with most stores retaining the brand until 2008-09.

[Ultra Food & Drug store]

500 Edinburgh Rd., Guelph, ON

Opened 13 February 1997 as Ultra Food & Drug. Presently serves as the only Metro store in the city of Guelph.

Odds & ends

And now for something entirely different! A coffee mug I happen to have, commemmorating Steinberg's 70th anniversary in 1987. The company wouldn't survive beyond its 75th.

Another blatant artifact: A Miracle Food Mart trailer! This one is moored in Thunder Bay, Ontario...where neither Steinberg nor Miracle ever operated, oddly enough.
