[8] After years of losses, parent company Steinberg's underwent in the mid-1980s a restructuring plan to rebrand the chain to the shorter name of M.[9] By then, Miracle Mart had made profits only twice since its founding.

[9] Four additional stores in Greater Montreal were converted to the M name by August 1986; specifically at Promenades Saint-Bruno, Place Longueuil, Mail Champlain and Pont-Viau.

[9] Four more stores, again all located in the Montreal area, were added to the M cluster on April 8, 1987: Châteauguay, West Island Mall, Place Lasalle and Galeries Lachine.

[15] Despite a good start, the M chain began to go downhill after the last Miracle Mart stores were renamed in 1987, and was soon experiencing the same financial woes that had plagued its predecessor.

[16] When Steinberg's parent Socanav was trying to sell parts of the company off, a buyer for the poorly performing M stores could not be found.

[20][21] On the 1992-1993 Montreal phone book directory, Bell Canada listed only four stores for the M retail chain; they are the three aforementioned mall locations that closed on August 29, 1992 and the other one at 4325 Jean-Talon Street in Saint-Léonard.
