Inside your raw files, there is a bunch of settings from your camera about how to develop the image (contrast, saturation, sharpness, etc). Some of these are grouped into "profiles" like Standard, Neutral, Vivid. Lightroom does not read this data. Instead, LR applies its own profile "adobe standard" for the initial viewing. In the Develop module, you will find the Calibration panel where you can pick a different profile including approximations to the profiles Canon put in the camera.
