Great Lakes Mesoscale convective complexs or MCCs can cause damage to wide swaths of forest and shatter glass in city buildings. These storms mainly occur during the night, and the systems sometimes have small embedded tornadoes, but more often straight-line winds accompanied by intense lightning. Historically, the Great Lakes, in addition to their lake ecology, were surrounded by various forest ecoregions (except in a relatively small area of southeast Lake Michigan where savanna or prairie occasionally intruded). Logging, urbanization, and agriculture uses have changed that relationship. In the early 21st century, Lake Superior's shores are 91% forested, Lake Huron 68%, Lake Ontario
Great Lakes Brewery (Toronto) Great Lakes Brewery (Toronto) Great Lakes Brewery is a craft beer brewery in Toronto, Ontario, Canada. In 2013 and 2014, Great Lakes won the top honour in Canadian brewing, named Canadian Brewery of the Year. Great Lakes Brewery was started in 1987 in an industrial unit in Brampton by Bruce Cornish and four other silent partners. The group produced two beers, an ale and a lager, using malt extract, a far cry from all grain used by craft breweries throughout North America. The beer was packaged in 1 litre plastic home brew bottles with a focus on the home retailer.
