May 21 (Reuters) - Boeing ( BA ) will invest a total of C$240

million ($176 million) in three Canadian aerospace development

projects as part of an agreement to sell Poseidon military

surveillance planes to Ottawa, the company said on Tuesday.

Canada and the United States reached a C$5.9 billion deal

agreement last November for the purchase of up to 16 Poseidons

and related equipment. As part of the agreement, Boeing ( BA ) agreed

to invest in Canadian enterprises.

The C$240 million, to be spent in the province of Quebec,

will be divided between an aerospace innovation zone, a center

focusing on a four-seat air taxi and a firm researching advanced

landing gear, Boeing ( BA ) said in a statement.

"These investments serve as a testament to Canada's aviation

leadership and exemplify Boeing's ( BA ) unwavering commitment to the

country," said Boeing Global president Brendan Nelson.
