Jan 29 (Reuters) - Canada's Trans Mountain Corp said on Monday that it had run into technical issues and faces new delays as it tries to complete the final part of expanding its oil export pipeline.

The company, which is part of the Canadian government, said it would take additional time to determine next steps to minimize delays. The company said it is aiming to put the expanded pipeline into service in the second quarter. (Reporting by Rod Nickel in Winnipeg; editing by Jonathan Oatis)
