Where can I watch Heartland in United States?

H.G. (Corey Sorenson) living a happy and openly gay life in New York must return to Iowa to help his alcoholic father save the family farm. He no longer feels he is a member of his family tribe but digs into the work along side his father and a hired hand, Ryan (Lachlan Neiboer), who has his own set of problems raising his younger brothers and sisters following the death of their parents. He comes out to his high school sweetheart, Dawn (Taylor Gwynn) who raises a ruckus at the nrews and outs him to the whole town, forcing his father to take to his bed with a bottle. Alone one night in the most desolate part of town he runs into Ryan and discover the farm hand is not exactly the ladies man people think he is.
