Metro, the gigantic grocery store chain with serious acreage at the northwest corner of Eglinton Ave. E. and Bayivew Ave., has just sold half of its 22 per cent ownership in the Couche Tard convenience store empire, also out of Montreal. You know Couche Tard (it means Night Owl) by its most famous Ontario name, Mac’s. Around here, Metro and Mac’s (in the Sunnybrook Plaza) look at each other across Bayview Ave. Now analysts at Credit Suisse say it might be a good idea if Metro took some of the after-tax $416 million it will get from the Couche Tard sale and buy the Rexall-Pharma Plus group in Canada. There is a Pharma Plus outlet in the Sunnybrook Plaza as well and another down by the Loblaw on Moore Ave near Bayview and on Mt. Pleasant north of Soudan. It all makes interesting reading in the Financial Post.
