Natural Resources Canada has extended FleishmanHillard's promotion of its tar sands energy resources for another year for $5.7M.

Environmentalists say development of oil sands intensifies global warming.

Opposition has crystalized over the debate of construction of the Keystone II Pipeline, which is supposed to transport the heavy oil resource from Alberta to US Gulf Coast refineries.

The Toronto Star reported that NRC is satisfied with the campaign's message "about the importance of the U.S.-Canada relationship, especially on energy.”

NRC's Jacinthe Perras said the push is “designed to raise awareness” and “ensure a fact-based dialogue” about Canada being a responsible supplier of oil and other resources."

FH's work covers the US, Europe and Asia.

NRC has spent about $23M during the past two years to promote its tar sands.

Its initial RFP said the promotion effort was necessary to to counter “intense and sustained PR campaign” launched by greenies and aligned groups.
