Last week the provinces signed an internal trade deal that is designed to remove domestic trade barriers that have hampered economic growth between the provinces for decades. The Canada Free Trade Agreement uses what’s referred to as a “negative list,” meaning that it automatically covers all sectors except where special exceptions are limited. Currently exempt sectors include taxation, water and tobacco. And while the deal postponed an agreement to streamline standards for moving alcohol across Canada, it did lay the groundwork for talks to establish a process to help provinces and territories regulate the trade of recreational cannabis. The deal will take effect on July 1st.
