CALGARY, Alberta - November 16, 2016 - News Release - TransCanada Corporation (TSX, NYSE: TRP) (TransCanada) today announced that it has completed its public offering of Common Shares. The Offering was announced on November 1, 2016 when TransCanada entered into an agreement with a syndicate of underwriters led by TD Securities, BMO Capital Markets and RBC Capital Markets under which they agreed to purchase from TransCanada and sell to the public 60,225,000 Common Shares which includes the full exercise by the underwriters of an over-allotment option granted to them.

The purchase price of $58.50 per Common Share resulted in total gross proceeds of approximately $3.5 billion.
