Thirty years later, it’s goodbye to the McDonald’s building that was part of the burger firm’s historic expansion of the 1980s. A giant backhoe is ripping up the parking lot Tuesday and will soon take down the former restaurant, second home to casual eaters and Leaside High kids. The site will become the “Leaside” LRT station at Bayview Ave. and quite possibly a good deal more. Metrolinx has consulted with developers about a large, maybe quite high building on this site and has purchased two of the four-plexes to the south on Bayview to make a sizeable footprint for this new building.
