The agency says the change largely reflected lower deficits on trade in goods and services.
It says the deficit on trade in goods declined by $400 million in the quarter to $1.7 billion as both exports and imports strengthened, with exports recording a larger increase.
The goods surplus with the United States remained at $11.2 billion, reflecting corresponding increases in both exports and imports.
The deficit on trade in services was reduced by $200 million to $5.8 billion, with lower payments on trade in commercial services and higher receipts on transportation services accounting for most of the changes.
The travel deficit remained at $4.3 billion.
