Anyone here have experiences with the Trans-Canada trail?

We tried a bit of it in 2006 and it varied from great to terrible. Great was the part in Quebec, from Riviere du Loup to Edmunston (NB). After that, the NB part of the trail became a joke (huge rocks, totally unusable on a bicycle). PEI was pretty good but we were told sometimes it gets taken over by ATVs..

Just wondering about the feasibility of using parts of it as we go across Canada this year. I know it's far from complete and the trail website isn't terribly useful on details.
