REGINA - Saskatchewan Premier Brad Wall is using Twitter to poke at federal NDP Leader Thomas Mulcair.
Wall takes issue with comments Mulcair made over the weekend while discussing the oilsands.
The NDP leader told a CBC radio program that the oilsands are artificially inflating the Canadian dollar and hollowing out the country's manufacturing sector.
He called it the definition of Dutch disease — a reference to the Netherlands and how a natural gas find in that country led to declines in manufacturing in the 1960s.
While the oilsands are largely an Alberta issue, Saskatchewan's economy is heavily dependant on resource revenue and Wall says he wants Mulcair to explain himself.
He says if Mulcair thinks the oilsands are a disease, Wall wants to know what the NDP thinks the cure is.
Mulcair told the radio program he wants to see the oilsands developed in a responsible way that sees more refining done in Canada and less raw product sent abroad.
