I hope this helps you . You are returning JSON as the page to the user following the upload. The JSON won't make any sense to a regular user, so most browsers doesn't have any predefined way to display the JSON.
If the returned page is displayed somewhere, you should return a regular HTML page that means something to the user. If the page isn't really displayed somewhere (e.g. loaded in a hidden frame), you should return an empty HTML page that all browsers know how to display.

Any of those help IE9 perfectly supports canvas.
If your page doesn't work fine it's usually because your header isn't right. Use this :
code :
    <!DOCTYPE html>
    <html>
    <head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />

This might help you Got it! Many thanks to Karl and his post here
The work-around is to use html2canvas.js, filesaver.js and canvas-toBlob.js for compatibility polyfilling.
code :
   <script type="text/javascript" src="html2canvas.js"></script>
   <script type="text/javascript" src="FileSaver.js"></script>
   <script type="text/javascript" src="canvas-toBlob.js"></script>
<button id="save_image_locally">download img</button>
<div id="imagesave" style="height:200px; width:200px;">
<img id='local_image' src='http://www.example.com/Images/Example.jpg'>
</div>
<script>
$('#save_image_locally').click(function(){
html2canvas($('#imagesave'), {
onrendered: function(canvas) {
var img = canvas.toDataURL()
canvas.toBlob(function(blob) {
saveAs(blob, "savedcanvasimage.jpeg");
}, "image/jpeg");
}
});
});
</script>

will be helpful for those in need It was already mentioned in the comments, but this does seem to primarily be an issue with Internet Explorer. You say that your PDF canvas is not drawing, but the library that you're using is drawing on a canvas. They even have comments in the code highlighting some of the issues around Internet Explorer.
As mentioned in the linked question, you might follow the advice of one those answers for handling IE issues. That might not actually help though, since its really the library that you're using that is causing the issue.
