no a shark has not been found in the great lakes but there has been a recorded attact but there is no proof that it was a shark and no proof that it wasn't.so we may never know if there is a shark in the great lakes.
No there have not been any documented sightings of great whites in Hudson bay.

Greenlands have been confirmed in shallow waters in the St Lawrence and even caught ice fishing in connected lakes in quebec. The porbeagle shark, a cold water shark may be in Hudson Bay.
