I was wondering if I import Envato fonts in Canva to create templates.
Hi @burtonbyc - welcome to the Envato forums 
It looks like you can add custom fonts in the OTF, TTF, and WOFF formats to Canva using their Brand Kit feature - there’s more information in their Help Centre here:

Brand Kits are currently available to Canva Pro, Canva for Teams, Canva for Education, and Canva for Nonprofits users.
