Look up your local cycletouring club and see what they're doing this year.
For example ...
The Elbow Valley Cycle Club in Calgary, AB has several multi-day tours:

I see that their longest upcoming multi-day tour is 9 days and goes from Hope to Barkerville, B.C.

Or here's the Vancouver Bicycle Club and their tours:

They've got a 9 day tour in August from Castlegar to Princeton
So have a look to see if your local club is going somewhere interesting, or if the touring club in the area where you want to ride, or near to where you want to ride, is going somewhere interesting.
-- Touring clubs like these are a great choice because their price is much lower than commercial touring companies. It might be a tiny bit more than doing a self-supported tour, but not much.
-- The tours I've done with the Calgary and Edmonton touring clubs have also had an element of flexibility to them. The Golden Triangle, for example, follows a set route, but you can leave when you want to leave as long as you've got your stuff on the van by a certain time. You can stop and eat at the many rest stops, or keep riding as you desire. You can ride as fast or slow as you want. You're under no pressure whatsoever to keep up with anyone. And you definitely do not feel remotely rushed. Once you arrive at the destination for the day, you're free to do whatever you want ... take a nap, go for a walk, ride some more, read a book, sit around and chat ... whatever takes your fancy. I did a hub-and-spoke tour with the Calgary club, and on that one we decided on our route for the day during a brief morning meeting each morning ... and different cyclists headed off in different directions each day. No fixed route at all.
-- The tours I've done with the Calgary and Edmonton touring clubs feed their riders VERY well. It's like a rolling picnic with a wide variety of excellent food.
Another option might be to check out Cycle Canada

They've got several supported tours, and they are more expensive ... but maybe that's what you're after. If you've got the money to spend, all the tours listed on their site look appealing to me!
