British Columbia Premier Christy Clark, right, and Alberta Premier Alison Redford chat prior to a closed door meeting in Kelowna, B.C. Friday, June 14, 2013. British Columbia and Alberta both have their reasons, but the bottom line is the two provinces are still wrangling over conditions linked to the proposed Enbridge (TSX:ENB) Northern Gateway pipeline, and those arguments have forced the last-minute postponement of talks between Clark and Redford.
