return_to on form dropping querystring/trackers

Using JS, I add my trackers to the return_to of any form on any page

 

<input type="hidden" name="return_to" value="/products/my-product?utm_source=facebook&utm_campaign=canada">

However, when someone completes the form it drops the querystring and returns to "/products/my-product". My conversion numbers are all out of whack because of it.

 

What gives?
