(Reuters) - AltaGas Ltd ALA.TO agreed to acquire Pacific Northern Gas Ltd PNG.TO for about C$230 million ($231.7 million) in cash.
AltaGas, which is involved in natural gas extraction and transmission, energy services and power generation, will pay C$36.75 a share, which is a premium of 20.5 percent to Pacific Northern stock's close on Friday.
In February, Pacific Northern, which delivers natural gas to customers in west-central British Columbia, had sold its 50 percent stake in Pacific Trail -- a 300-mile joint venture pipeline originating at Summit Lake, British Columbia.
