Need help with Canvas issue

I have recently got into Unity and I completed the Space Shooter tutorial. I then went on to expand and add more features to this game as I wanted to learn as much as I could about unity.
I found a GUI tutorial and followed it and it works perfectly in it’s own scene. Here if you’re curious.(

)

My issue is, I copied and pasted the entire Canvas from the scene it was working in, into the scene for my Space Shooter. The canvas will show up however all buttons do not respond to mouse hover and do not respond to being clicked.

I have the canvas set to the UI layer as well as giving it its own sorting layer and have made sure nothing is above it in the scene. I’ve tried a couple Raycaster options to see if that was an issue and I had no luck.

I’ve tried Googling the issue but as yet have not found any solution. Just wondering if anyone has an idea as to what the cause may be.

Thanks.

Nevermind, found the solution. Missing EventSystem. Sorry.
