The building that housed the nation’s last full-time sardine cannery is being auctioned after a lobster company that bought the property defaulted on a loan. The plant in Gouldsboro and a wharf in Stonington owned by Massachusetts-based Live Lobster Co. are being auctioned Wednesday. A lease held by Live Lobster on a pier in Phippsburg is being auctioned Thursday. The auctions were ordered by TD Bank, which sued last spring claiming Live Lobster owed it $3.4 million. Tranzon Auction Properties says it’s had inquiries about the processing plant from the U.S., Canada and China. Live Lobster bought the former Stinson Seafood sardine cannery after it shut its doors in 2010. The plant employed about 70 people in the summer of 2011, but it shut down operations in March.
