OTTAWA, June 19 (Reuters) - Canada's labor relations board is deliberating whether to intervene in a dispute at the WestJet airline involving aircraft maintenance engineers, a government source said on Wednesday.

The source, who requested anonymity given the sensitivity of the situation, said the Canadian Industrial Relations Board could take a range of actions, including ordering arbitration.

Labour Minister Seamus O'Regan on Tuesday said he had asked the board to take up the matter. (Reporting by David Ljunggren, editing by Ismail Shakil)
