Statistics Canada says wholesale sales, excluding petroleum, petroleum products, and other hydrocarbons and excluding oilseed and grain, fell 0.6 percent to $82.4 billion in June.
The agency says sales fell in five of the seven subsectors.
Sales in the motor vehicle and motor vehicle parts and accessories subsector fell 2.6 percent to $14.2 billion as the motor vehicle merchant wholesalers category fell 2.7 percent to $11.5 billion.
The machinery, equipment and supplies subsector dropped 0.5 percent to $17.9 billion in June.
In volume terms, wholesale sales fell 0.9 percent in June.
Statistics Canada started including oilseed and grain as well as the petroleum and petroleum products subsector as part of wholesale trade last year, but is excluding the data from monthly analysis until there is enough historical data.
