Layering an image on top of an HTML canvas that already has an image as its background

Question

I created a canvas element with a colored background, and I came up with the following code to insert an image on top of this canvas:

    const canvas = document.getElementById(id);
    console.log(canvas);
    if (canvas.getContext) {
        var context = canvas.getContext('2d');
        var img = new Image();
        img.src = 'https://google.com/xyz.jpg';
        img.onload = function () {
            context.save();
            context.rect(10, 2, 10, 10);
            context.clip();
            context.drawImage(img, 0, 0); // image won't resize 
            context.restore();
        };
    }

Now this successfully layers the image on top of the canvas (it's cut off however), but I can't find a way to resize the image to be of a certain size (for example 10x10). I tried changing changing the second last line in my code to context.drawImage(img, 0, 0, 10, 10); but this broke my code and the image would not display on the canvas at this point. Any help would be greatly appreciated!

To load and draw an image.

const ctx = can.getContext('2d');
const img = new Image;        
img.src = 'https://pbs.twimg.com/media/DyhGubJX0AYjCkn.jpg';
img.addEventListener("load", () => {
    // draw image at 10, 10, width and height 50,50
    ctx.drawImage(img, 10, 10, 50, 50);  // resizes image
}, {once: true});
    

canvas {
   background: green;
}

<canvas id="can" width="200" height = "200"></canvas>
