Not a problem
Lightroom Classic: Trouble with Canon 5d Mark III aspect ratio
Today I imported RAW images I shot on the Canon 5d3 with the camera set to Add Cropping Information set to 4:5 ratio. Crop lines are displayed on the camera LCD but you see the full frame outside of the crop when review files. Alarmingly, when I imported them to LR 4.1 RC, the images appeared cropped to 4:5. I though ok, I'll just go to the crop tool and I will see that a crop has been applied and I'll remove it. Unfortunately, there was no file beyond the crop lines, it could not be removed as far as I could tell. I called Canon and they told me to try Digital Photo Professional, a program that I never pay attention to. Sure enough, the images were intact when viewed there. There appears to be a bug when LR 4.1 RC encounters the crop tag on the raw file.

With that in mind, I think it is a duplicate of http://feedback.photoshop.com/photosh...
P.S. The raws can be fixed using exiftool with option -m and the tags aspectratio, aspectframe, CroppedImageWidth and CroppedImageHeight (depeding on camera), but this may be risky depending on the raw format.
P.S. II: Proposal: Instead of "hard cropping" such raws, LR should apply a "soft crop" using its standard cropping tool on import. Using this method, the information in the metadata is not lost, but can be overridden anytime by the user. Furthermore, the crop tool can be modified that it contains "Original" (= crop as the camera settings) and "Full Frame" (= whole raw image area). A reset of the crop tool or the develop settings should revert it to "Original".
However, I see a problem here for photos already imported in LR3+4 using "hard cropping" because they have to be converted to "soft cropping", taking into account existing "soft cropping" and the coordinates of local corrections. Tricky, but should be manageable.

It's my first LR plugin, so it is quite possible that it still is somewhat buggy. So far I only tested it with Olympus ORF raws.

I wish there was a way could have the crop marks displayed on the back of the Mark III without impacting the actual image. As it is nice to be able to view the 4x5 ratio as a reference.

I did try removing the crop in Canon DPP and re-saving, didn't work. Even tried removing crop and doing a save-as, no fix. If you remove the crop and save as a tif file, the crop is removed, but the file quality was degraded.
Also PO'd at myself for not verifying the crop data feature before shooting a bunch of photos.
The worst part may be watching LR4 crop the image as it is being imported. That is rubbing salt in the wound.!

Unfortunately, the command is a little different for different cameras, probably because the crop information is in a proprietary format. I don't know the correct command for a Canon. You will have to look in the exiftool output for a cropped and an uncropped image to find out what is different.
Perhaps you can find some inspiration in the commands for Sony and Olympus:
For Olympus, you can use this:
exiftool -AspectRatio=”" -AspectFrame=”0 0 0 0′′ -DefaultCropOrigin=”" -DefaultCropSize=”" -o target_filename.ORW source_filename.ORW
For Sony, you can use this to change a cropped height of 3376 pixels to 4000 pixels on a 24 MP sensor:
exiftool -sonyimageheight=4000 -exifimageheight=4000 -o target_filename.ARW source_filename.ARW
