I don't care what anybody says 13% dividend yield is not sustainable and dividend will be cut 50% soon and share price will get another 10-20% haircut (if oil stays at 50$ or else it can be another 20-30%).
If somebody wants to buy Canadian oil and gas presently, it's well advised to go to the best names: SU, CNQ, HSE, maybe CVE. Everything else is playing with fire.
