morning growmie… you probably meant ‘thin out’ …I see light thru so IMHO no…
You could pick off 2 or 3 of those lower leaves that are going to touch the soil. If air can pass through it there isn’t much need to prune especially if it stays outside.
Welcome.
Agree with above
Welcome to the community @67yrold1sttimer!
I don’t see any need to pull anything yet. I do tend to take the ones off the soil though.
The Pros know and they got you up top already yo!!! The only thing I can add is welcome to the Canna-Fam Growmie
Good looking plant you got there 
From one 67 oldster to another. I think she looks great. Welcome to the neighborhood.
