You "can" use it for entry in Canada, but to do so, unless you already have a Work visa, can be counterproductive. Since it is meant only for business travel, you will draw the attention of their immigration officers, and if you don't already have said visa, be prepared for a grilling about just what business activities that don't require a visa you might be undertaking.
