Aligning while using artboards vs. without is different, why?

[vanillalily]

I'm wondering if anyone can help me as I assume this is a setting. 

When using artboards I can select an item and the align buttons in the toolbar are accessible and I can just align to the artboard without requiring select all. When I'm using just a canvas without artboards I can't. When I select an item the align buttons are greyed out. 

Is there a setting that I can change so that I can align to the canvas without having to select all each time?

Thanks in advance for any help!

I'm not in front of a computer, but with the move tool active, look under the three dots or the gear/cog icon, there's a drop down menu with alignment options for either selection or canvas.

Thank you! So that allows me to align with canvas, so that's amazing BUT now everything will only align with canvas. If I select 2 or more items they will all align with artboard, not each other. If I'm using artboard I can select 2 or more items and they will align among themselves without aligning to the canvas. 

I hope that makes sense. 

Side note: When I compare the settings between artboard and non-artboard files, artboard does have it as selection, not canvas, it actually can't be changed to canvas either.

Select all before aligning has been a long standing hack to achieve the same result as align to canvas when in selection mode.
