Check Box DataBinding / MinWidth Problems

I am creating a UWP application and I want a simple check box, no text, for each entry in my ListView. If I add a checkbox control to my template for the listview, I get a big gap after the checkbox for the Content - event when the content is empty.

If I turn on multiselect in the listview so I get a nice checkbox for each row, I can't seem to figure out how to databind the check box for each row in the listview to the Selected property of my ViewModel.

Below is a picture of what I want the area of the check box to look like. This was generated using the SelectionMode="Multiple" on the listview. Remember - the problem with this approach is I can't seem to find a way to bind the check box to the Selected property of my ViewModel class.

Below is what it looks like if I remove the SeletionMode property and add a check box to my ItemTemplate. As you can see there is a huge gap between the check box and the area where the image will be due to the Checkbox control's minimum width of 120.

Any suggestions would be greatly appreciated.
