I need some help. My EOS 70D has started to have grey vertical line in every picture.
Despite all of that, the line shows up when you review the pic on the camera as well as the actual picture when viewed from the card.

That is most likely a fault with the image sensor itself or with the electronic interface to it. You need to contact Canon, hopefully it is still in warranty but otherwise they can help you decide upon a course of repair.
When you get such a perfectly straight line, it won't be from external debris but instead is a problem with a component.
One column of the sensor isn't being properly scanned so you have null data from that column of sensor cells.
