The need for such an agreement is clear. Over time, many differences have emerged in the rules adopted by these two provinces; Rules which, unfortunately, hinder the free movement of goods, services and people. This situation increases the cost of the activity, reduces productivity and makes it more difficult for people to move for a job. Prior to Saskatchewan`s participation in the agreement, the combined economy of Alberta and the BC was already the second largest “free trade area” in Canada – behind Ontario in size, but far ahead of Quebec. Saskatchewan`s inclusion in the mix expands the size of the area by an additional $69 billion (Saskatchewan`s nominal GDP in 2008), bringing total triprovincial GDP to nearly $550 billion.
