REGINA: The hefty pay raise for the Saskatchewan Union of Nurses (SUN) is just one more reason the province should pave the way for private sector health care, according to the Canadian Taxpayers Federation (CTF). SUN's latest contract offered a 35 percent wage hike over four years. Meanwhile, health spending went from 34.8 percent of provincial spending in 2006-07 to an expected 43.7 percent in 2008-09.
