The agency says there were decreases in five of the seven subsectors in February, including machinery, equipment and supplies.
It says these declines were mostly offset by higher sales in the motor vehicle and parts subsector.
The largest decrease in dollar terms was in the machinery, equipment and supplies subsector, where overall sales fell 2.1 per cent and the second-largest drop was in the personal and household goods subsector, where sales were off 1.5 per cent.
The largest advance in dollar terms was in the motor vehicle and parts subsector, where sales rose 3.0 per cent.
Wholesalers in seven provinces reported increased sales in February, but these were largely offset by a 1.1 per cent decline in sales in Ontario.
