Custom camera profiles only address hue, luminance, and saturation. I'm sure Canon's DPP camera profiles are more complicated than what I can make myself. I guess I'll have to try it and see what happens.
Canon (DPP or in-camera) uses "Picture Styles" which are preset packages that contain a profile plus contrast, saturation and sharpening settings. However, the P.S. can be modified quite easily by changing the contrast, saturation and sharpening elements either in-camera or by pushing sliders in DPP. Even the profile can be altered with the Picture Style Editor software supplied by Canon.
In LR/ACR these parameters are independent but can be bound together in a User Develop Preset. You can start with selecting one of the DNG Camera Profiles that are designed to simulate the various P.S. profiles used by Canon. They are not identical (considering that they had to be reverse-engineered, that would be too much to expect), but they are quite close and, as Dinarius writes, work quite well. Next you have to find basic settings for Contrast, Saturation/Vibrance and Sharpening that fit your taste or (if that is what you really want) imitate DPP. Create a Develop Preset, give it the name of the Canon P.S. to which it correlates and set it to be automatically applied at import to LR or file opening in ACR.
Making your own profile instead of using one of Adobe's Camera Profiles is, of course, a possibility, but I think you will find that you derive the most benefit from a Color Checker profile when it is made for specific and unique lighting conditions, while for sunlight and non-specific artificial light they do not give much added value beyond Adobe's profiles.
