Canvas and canvass sound alike, but they do different jobs.
Canvas is usually a noun. It means a strong fabric, or the cloth surface used for painting. You might buy canvas for a tent, shoes, or an art project. Example: The artist primed the canvas before starting the portrait.
Canvass is usually a verb. It means to ask people for votes, opinions, or support. It often appears in politics, surveys, and outreach. Example: Volunteers canvassed the neighborhood to hear what residents thought.
A simple memory tip helps: canvas is a thing, while canvass is an action. If you can touch it or paint on it, use canvas. If you are going door to door, collecting views, or seeking support, use canvass.
- She painted on a large canvas.

When you are choosing between them, ask whether you mean a material or an outreach activity. That usually makes the correct choice clear.
