Here in Canada, each province has at least one cycletouring club. For example, Manitoba has the Winnipeg Cycletouring Club. Alberta has the Edmonton Bicycle and Touring Club and the Elbow Valley Cycle Club (in Calgary). If you were travelling through Canada, just do a search for a club in one of the cities or provinces you're going to and check their Links page. Many of them will list other touring clubs across Canada, plus other clubs within the province.
This is Edmonton's club's link page: http://www.bikeclub.ca/pages/links.html
You might also check out the links for Randonneuring clubs ... even if you aren't into ultra distances. Many Randonneurs also tour, and many of us are into all sorts of other types of cycling. Not only that but we know the roads for many, many kilometers around where we live because we're cycling hundreds of kilometers each week. At the very least Randonneurs are probably some of the most knowledgable cyclists for route info not only because we ride so much, but also because many of us plan "official" routes for our events, which involves a lot of scouting.

where you can find clubs all over the world (heavy on North America and Europe)
If you're in England, check out the CTC: http://www.ctc.org.uk/
... I had the pleasure of riding with a CTC club on two occasions and thoroughly enjoyed it. The club I rode with were definitely not out to race or to set any speed records ... they just ride for the fun of riding, and I loved that!
