Answer 1

All Canadian Lakes thaw out in summer. If not they are glaciers.

The thaw begins about two weeks after your New York timing, and finishes by May 30 below the Artic Circle. Above the Artic circle to the mouth of the MacKenzie River the rule of thumb 30 years ago was June 15th.

Global warming has changed this date. Worse still the thaw it is not as consistent as it was. In an El Nino the storm pattern is changed. So then the lakes stay open later in the freeze up and thaw later than normal.

Freezing of the lakes is a very important function to the bio-systems in northern lakes. It triggers spawning behavior for instance. It keeps foreign species from invading.

Lake Superior, the largest of the Great Lakes normally doesn't freeze over completely. It has frozen over twice in the last fifty years in abnormally cold years. Lake Ontario and Lake Erie don't freeze over these days either. Thirty years ago, they did.

Most lakes north of the Great lakes freeze over. This is not the bad thing. In Northern Ontario the freezing of the lakes creates highways. Ice roads are created where none existed and the years supplies go into remote communities in that part of Canada.

Having grown up in Northern Ontario I saw that the freeze up enables people to go over lakes and swamps(that are called muskegs) far more easier than in the summer time in the heat and biting insects that inhabit the thick forests.

Forestry and exploration drilling activities are more active in winter than summer. The snow and ice allow people to move themselves on snowshoes, skis and ski-doo's over great distances. So its not a bad thing at all.
