Ontario has the "Onroute" stops every 70-100km along the major highways (Between Windsor, Montreal, and a couple on the 400 north). Typically there is one on both sides of the highway so that they don't need to build a major intersection, just a simple merge lane.
It would be great to have a couple of similar options along our highways. However, the article linked above sounds like the opposite will likely happen with the Petrocanada at 22/1 with their move being proposed to be further off the highway then it currently is.
