Info from Canadian site:
*Cod in the Canadian area are divided into stocks which are defined as recognizable units displaying characteristics unique to each stock with very little intermingling between adjacent stocks. The stock division serves as a very useful management unit for management of the cod resources. Cod stocks in the Northwest Atlantic area are:

#1. West Greenland (NAFO Div. lA-lF)
#2. Northern Labrador (NAFO Div. 2G + 2H)
#3. Southern Labrador-Eastern Newfoundland (actually a stock complex composed of several large interrelated stock components) (NAFO Div. 2J + 3K + 3L)
#4. Southern Grand Bank (NAFO Div. 3N+30)
#5. Flemish Cap (NAFO Div. 3M)
#6. St. Pierre Bank (NAFO Div. 3Ps) Northern Gulf of St. Lawrence (NAFO Div. 4R + 4S + 3Pn)
#7. Southern Gulf of St. Lawrence (NAFO Div. 4T + 4Vn)
#8. Northern Scotian Shelf (NAFO Div. 4Vs + 4W)
#9. Southern Scotian Shelf (NAFO Div. 4X)
#10. Gulf of Maine (NAFO Div. 5Y) Georges Bank (NAFO Div. 5Z)
