Hyperbole?

>Much of the landform has been shaped by the actions of glaciers and the shrinkage of the bay over long periods of time

This would support your notion. Albeit ridiculous.

>Finally starting in the Late Ordovician and continuing into the Silurian did the gradual regional subsidence of this part of the Canadian Shield form the Hudson Bay Basin

This would not.

I cannot decide whether to laugh, or downvote your comment without more context. That I did some research and learning to decide to comment instead leaves me happy and satisfied that your comment was not completely worthless.
