Absolutely not.

I recently drove past my childhood home. The canvas awnings that were there 30 years ago are still there, and look fine. Almost everything else about the house has changed.

How do you know it was never replaced? If it was the same, I'd be concerned about how much PFAS or other forever chemicals were used

Canvas has been canvas for an exceedingly long time right? Has anything about it really changed?

Treating canvas for fire and water resistance has been done for a long time for some applications. I don't know what is used for that, though.

Scotchgard was a PFOS based formula changed to a PFBS formula brought to us by our lovely friends at 3M.
