The Finance Department says the federal deficit was $14.5 billion between April and October.
That compares to a $15.1 billion deficit over the same period last year.
According to the monthly fiscal monitor, revenues were up $26.5 billion, or 10.7%, compared with the same stretch in the previous fiscal year as revenues rose in all categories.
The finance department says program expenses excluding net actuarial losses were up $22.7 billion, or 9.8%, driven by increases in direct program expenses, major transfers to persons, and major transfers to provinces, territories and municipalities.
Public debt charges were up by $5.3 billion, or 19.4%, mostly reflecting higher interest rates on marketable bonds and treasury bills.
Net actuarial losses were down by $2.1 billion, or 46.8%.
