Hello Santosh,
The template itself also has a commercial license. Just now I had to re-read the terms and conditions on the Bubble marketplace, and I found myself quite confused, too.
As mentioned in this thread from last year, templates with Commercial licenses that cost $0 show some text in the Marketplace that suggest that they come with an Open-source license. Template and Plugin Licensing Clarification - #5 by luke2
I found the licenses for the templates by using the Google Chrome devtools on the page Templates | Bubble, since I couldn’t find it displayed anywhere else.
Sorry for the confusion here, and hope you’re still interested in using Canvas for your client projects or for your own projects.
Kind regards,
Chris
