Dec 13 (Reuters) - Air Canada ( ACDVF ) decided to

introduce carry-on baggage fees for some customers to stay

competitive with changing market forces in the country, a

company executive told a parliamentary committee on Friday.

Earlier this month, Air Canada ( ACDVF ) said it would charge

passengers for bigger carry-on bags if they opted for its

lowest-priced fare for North American and Caribbean routes

starting on Jan. 3.
