Best way to make a Next Level Screen

Hi, i am making a game, and want it so when the player passes the finish line it shows a screen that says, "You completed Level (some number) in (some amount of time) then have a button that says next level and when they click it, it sends them to the next level. Now would i want to do this by having a GUI canvas show up when the player passes the finish line? or create a whole different scene that loads when the player passes the finish line?

 

Better to create a UI canvas. Its easier that way.

 

Okay, thank you!
