TransCanada has already invested US$2.4 billion in the project and major customers still stand behind it. The company is working hard to address ongoing roadblocks, but investors should probably look at Keystone as a bonus at this point when deciding whether or not to buy the stock. Energy East is TransCanada's $12 billion project designed to carry crude oil from western Canada to refineries in Quebec and New Brunswick. The project requires the construction of new pipelines across six provinces as well as building new terminals and converting an existing natural gas pipeline into one capable of transporting crude oil. The company already has contracts in place to cover one million of the 1.1 million barrels of shipping capacity. Provincial and municipal governments are still negotiating with TransCanada regarding the pipeline routes and that process could drag out longer than expected. At the moment, TransCanada is targeting 2020 as the in-service date.
