If you send your return through NETFILE, you would need to find your confirmation number. This is proof that your return was filed successfully. https://turbotax.community.intuit.ca/questions/1518044-how-do-i-find-my-netfile-confirmation-number

If you sent your return via post, unless you sent it via registered mail, there is no way to be sure when/if the return was delivered to the CRA. If the CRA didn’t get it, then it may not have arrived.
