Use CSS for layout, Javascript is not good idea for layout.

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0">
<style>
body {margin:0; padding:0;}
#parent {
    position:absolute;
	background-size:100% 100%;
	background-color:blue;
	width:100%;
	height:100%;
}
#theCanvas {
	background-color: red;
	width:100%;
	height:100%;
}
</style>
</head>

<body>
<div id="parent">
    <canvas id="theCanvas"></canvas>
</div> 
</body>
</html>

background-size() is CSS property and is does not exist in JQuery. And for the JavaScript syntax is

object.style.backgroundSize = “60px 80px”

One minor issue, in this example, don't need the position css setting. And suggest to be careful to use the absolute position, it's will cause some tricky issue if there are many other tags under body. :)
