Canada competition watchdog will not challenge Agrium, Potash merger

OTTAWA, Sept 11 (Reuters) - Canada's competition watchdog said on Monday it will not challenge a proposed merger between Agrium Inc and Potash Corp, saying the transaction was unlikely to substantially lessen competition in the fertilizer industry.

The Competition Bureau said it had issued a "no action" letter to the two companies, which announced their plan to combine last year in an all-stock merger valued at $25 billion. (Reporting by Leah Schnurr; Editing by Sandra Maler)
