Pan I do believe the info on the back of the awning tape package list canvas.
Myself, I'd put my money on an iron-on patch made for boat cover repairs. If you can not remove the canvas from the pop-up, place a hand towel (or similar) on a piece of plywood and have a helper hold the backerboard in place as you iron the patch in place. If the tear is on a curved area of canvas use a larger towel folded or rolled to fit the shape and follow the contour slowly with an iron, assuring the patch adheres as you go.
For iron-on patches made for clothing you can cover the first patch with a larger patch then treat the area with water proofing silicone.
If the situation permits put a patch on the inside too. Just remember the inside patch could be affected when installing the outside patch so watch the heat application.
It is important to clean the area first and I've had good results using Fantastic then letting it throughly dry.
Applying patches with rounded corners is recommended.
For what it's worth here is an ad taken from Menards.

Yep.... sez boat sails and pop-ups too😁
