Doing that, I think, would be more like
canvas.toDataURL(“image/svg+xml”);
Instead, it seems to me that he wants to use SVG commands to draw on the Canvas. If so, this is already possible indirectly.

var can      = document.querySelector('#my-canvas'),
    ctx      = can.getContext('2d'),
    loader   = new Image;                       // Not shown on page

loader.width  = can.width;
loader.height = can.height;
loader.onload = function(){
  ctx.drawImage( loader, 0, 0, loader.width, loader.height );
};
var svgAsXML = "<svg xmlns='http://www.w3.org/2000/svg' "
             + "width='"+can.width+"px' "
             + "height='"+can.height+"px'>"
             + …the rest of your code…
             + "</svg>";
loader.src = 'data:image/svg+xml,' + encodeURIComponent( svgAsXML );
