I copy this one from HTML Course

Canvas
- Elements are drawn programmatically
- Drawing is done with pixels
- Animations are not built in
- High performance for pixels-based drawing operations
- Resolution dependent
- No support for event handlers
- You can save the resulting image as .png or .jpg
- Well suited for graphic-intensive games

SVG
- Elements are part of the page's DOM (Document object model)
- Drawing is done with vectors
- Effects, such as animations are built in
- Based on standard XML syntax, which provides better accessibility
- Resolution independent
- Support for event handlers
- Not suited for game applications
- Best suited for applications with large rendering areas (for example, Google Maps)
