The eastern spruce lumber market lost some of its steam yesterday. The activity was not as robust, and the demand was not as prolific as it has been. Hot weather across the country was one reason for the slowdown along with clients feeling they had enough stock for the time being. It was difficult to convince them otherwise. The mills tried their best to sell what they did have available but ran into strong resistance. Several eastern Canadian mills begin their summer holiday shutdowns today with production and shipments impacted in varying degrees.
