CALGARY, Alberta, Nov 22 (Reuters) - TransCanada Corp TRP.TO is "cautiously optimistic" about the chances of its Keystone XL pipeline after the state of Nebraska denied the company's preferred route, the leader of the oil producing province of Alberta said on Wednesday.
Premier Rachel Notley's comments were the first indications of the company's stance on the announcement on Monday from the Nebraska Public Service Commission. TransCanada has so far said only that it will evaluate the decision.
