I had mailed my tax back in March and my past Employer has just recently received it and returned to sender! How do I go about changing my address and resending?

When you say that you mailed your "tax back in march" do you mean your tax return? Because you are supposed to mail your tax return to the Canada Revenue Agency (CRA), not to your employer.

If you need to change the address on your return, you can login to TurboTax Online, open your return, and then select My Info > Contact Info from the left side menu.

To print your return to mail it again, select File > Filing Hub from the left side menu, and click on the Print & Mail your Return(s) button. There is a link on that page to download the PDF to print, as well as a link that list the CRA's mailing addresses.
