X00008 Is the person in this photo Lawrence Ashton - Solved!

I have previously posted about a photo of a 75th Battalion soldier that I found on ebay that I was wondering whether or not was Lwarence Ashton or not.

Here's the photo from ebay:

Recently someone posted a different photo of Lawrence Ashton that I hadn't seen previously:

This photo is nice a clear and I can definitely see that it is the same person as in the other known photos of him. But the person in the ebay photo is definitely someone else.

Is the person in this photo Lawrence Ashton?

A few months ago, I purchased a picture below off ebay:

The picture is of a WW1 soldier and the uniform indicates that he was in the 75th Battalion CEF. My thoughts (and main reason for purchasing the photo) were that this could possibly be my great-grandfather, Lawrence Ashton, who was in the 75th Battalion CEF. I have included some pictures below that are of him for comparison. Any thoughts as to whether he might be the same person as the one in the ebay photo? I've asked a few people and have received different opinions.
