This is usually due to different default RAW rendering profiles, not a problem with the file.

Canon DPP uses Canon’s own color science and picture style rendering, while Lightroom uses Adobe’s default interpretation unless you choose a camera-matching profile. That can make the same CR2 file look noticeably different in color, contrast, and white balance.

For a closer match in Lightroom, set the Develop module’s Camera Calibration/Profile to a camera-matching option such as Camera Standard. That was the fix reported here, and it makes Lightroom’s rendering much closer to DPP’s default look.

Also note that the two programs may apply different white balance by default. Comparing the RGB histogram of the same neutral area can show this: if one converter has a lower red channel than the others, its white balance will look different.

So the short answer is: Lightroom is not “bad,” it is just using a different default RAW profile. Choose a Canon-like camera profile in Lightroom if you want results closer to DPP.
