Revision 2: 188 players total

Thanks to everyone for their contributions to a complete list. I neglected to check out the Sacred Heart roster, which is technically also a D1 program. So that adds 2 more to the total. Aldous from Windsor doesn't qualify, as she was from the Ontario class that graduated the previous year. Also, as I've chosen to track only Canadians to D1, the Bero girls wouldn't qualify either despite previously playing here.
