In theory, that is what makes the difference. In Alberta, for example, six nurseries sell their products to a cooperative, which in turn distributes the trees. The people in the nurseries do not know if the trees are going to be used ornamentally, for reforestation, or for soil rehabilitation. They do not know. It is the same in Quebec. Most of the trees are probably going to be sold to the government, but the government can provide them to the ministère des Transports or to schools just as easily. In many cases, we have no way of tracking where the products go.
