Politicians failed to pass the bill Thursday, and Premier Alison Redford is expected to dissolve the house on Monday to call a general election.
The bill came under fire from home-schoolers who feared they could be hauled before human rights panels for teaching their values to their children.
Education Minister Thomas Lukaszuk (loo-KAH'-zuhk) has said that wouldn't happen.
But with over a thousand home-schoolers protesting at the legislature this week, the government did not appear keen to pass the bill.
The Tories passed up a chance to limit debate, talked out the clock, and then cancelled the evening sitting.
