If you are referring to Trans Core (Link Logistics), yes they are very expensive. However, they do have the market in Canada pretty much wrapped up and to date, no alternative platform has been able to establish themselves. One thing we have done is to subscribe to the minimum service required for your specific operation. Add some of their other offerings later if you think you need them.
I use ITS for my Canada-US freight and intra US.. seems to work well. For my domestic Canada I don't really need a load board.. small market characterized by overcapacity.. can usually come up with a truck via a couple of phone calls.
