Fun fact, evergreen trees (what we are actually talking about are coniferous trees) existed before angiosperms (which we are referring to as deciduous on here) and at that time the world was far warmer than it is now.

I you look at the deciduous forests in southern Ontario and southern Quebec, you'll find them in the Saint Lawrence lowlands. Once you step into the Laurentians (Canadian Shield-Boreal transition) or in the Appalachians (New England/Acadian Forests), the types of tree species change radically.
It has to do with the altitude, the latitude and the type of soil. Much of the St. Lawrence Lowland is underlain by clay deposited in the Champlain Sea.
