MSP and (im assuming) YYZ have great snow removal, that probably played a key factor. If the runway was covered in 1in of snow I could see using the loc to help identify the runway, if what the other posters say is true and the 145 would show the loc offset by 100' that could have been the recipe that led to this. glad everyone is ok and hope the cvr makes the crew look good
