"The only realistic alternative to the closing of line 5 would be to reactivate the old Portland Pipeline system and reverse Line 9 once again but that would yield only 240 Kbpd versus 540 kbpd required"
I am not an authority on the Canadian pipeline network, but you might find this article interesting re alternatives to line 5:

In particular, the article provides an interesting map and makes reference to "line 61":
"Line 5 is part of a network of Enbridge pipelines called the Lakehead System. As Line 5 cuts east and then south around Lake Michigan, Line 61 runs south from Superior into Illinois before connecting with smaller lines that cross Indiana and Michigan and ultimately reach the same destination: Sarnia, Ontario.
Line 61 is newer and larger — the 42-inch pipeline was completed in 2009 and has already undergone multiple upgrades and expansions. The line carries about 996,000 barrels per day to Pontiac, Illinois — about 75% of its capacity."
Is this consistent with your observations about the Portland link?
