MONTREAL -- Bombardier Aerospace says it has received an order for three of CS300 in an order valued at about $228 million US.

The Montreal-based company says the order came from an existing customer that has asked to remain unidentified.

The CSeries aircraft are designed for the 100-to-149 seat market.

Bombardier says Sunday's order boosts the number of orders and commitments to 445 CSeries aircraft.
