You can choose to create an online Business Model Canvas right here at Canvanizer. It is the first option you see after clicking on Create Your Own Canvas. Otherwise, a quick Google search on the term will lead you to many sites that allow you to download a pdf version of the template.

Canvanizer 2.0 also allows downloading your finished canvas in PDF or png format.
Canvanizer 1.0 allows to download and export the texts, a slideshow and csv, but can’t technologically export PDFs or PNGs.
