Canada offers tax incentive on capital investment to lure foreign investors

Carney also said Canada was seeking private investment through long-term concessions to operate the nation's four largest airports - Toronto, Montreal, Calgary and Vancouver.

"(We) will retain ownership of the underlying land and assets, but we will unlock their true value, by bringing in new capital and expertise into their operations and growth."

Speaking on the sidelines of the summit, two asset managers told Reuters they would be interested in investing in airports.

Canadian labor groups have said they oppose privatization, arguing that it would raise costs for travelers.

As a result, Canada’s marginal effective tax rate on new business investment will fall from roughly 13% to 6.4%, the lowest of any major economy in the world and less than half the rate in the United States, the government said in a statement.
