For changes from one channel number to another, there is a message left on the original channel indicating the new number. Larger updates can be found at telus.com/tvnews
Crave is no longer on the main on demand page but you should still be able to find it by pressing the on demand button and choosing TV On Demand > Movies and Series > Crave. As you mentioned, it's also available on channel 411.
I apologize for the inconvenience of having to look for the new location.
