The Conservative government budget in March forecast that the deficit for the fiscal year 2013-14, which began in April, would shrink to C$18.7 billion from C$25.9 billion in the prior year. It promises budget balance by 2015.
The April deficit shrank to C$283 million from C$713 million in April 2012, while May's grew to C$2.43 billion from C$1.11 billion a year earlier.
A 3.6 percent rise in program spending during the two months outstripped a 1.4 percent increase in revenues. Public debt charges also rose by 2.0 percent, reflecting higher inflation adjustments on real return bonds.
