There is no safe way to transport tar sands oil:
A major train derailment has occurred near Wadena, Sask., prompting authorities to keep people well back from burning railcars and huge plumes of smoke that may be toxic.
The CN Rail derailment happened at 10:40 a.m. CST Tuesday about 20 kilometres west of the town of 1,300, which is about 230 kilometres east of Saskatoon.
Officials are worried about toxic smoke from the burning cars and are keeping people eight kilometres from the scene.
Six of them contained hazardous materials, including four that had either hydrochloric acid or caustic soda. … The other two had petroleum distillates, CN said.
