Hi.. It worked for me and I have received AOR thankfully.
I have done the following:
1-Sent the correctly signed form together with an explanation letter containing all relevant information about the application package. Date sent, date received, courier tracking number, applicant’s info.. sponsor’s info, adress from where the package sent and fees receipt number “ which you received when you paid your app fees and starts with R”.
2- sent the form with the explanation letter by regular mail to the same adress where I sent the original package.
3- My husband called IRCC on their line from inside Canada to explain and request that the 2 packages to be linked together. We had a nice agent who understood the situation and promised to help.
Not sure which way from the above was effective but I recommend you to do the same. I adviced someone who did the same mistake and it worked for them as well. But to be honest, it depends on the officer who is handling your application and the officer received your request. In all cases you should give it a try and see.
Good luck.

our application hasn't received yet.I tried to return my application from courier service but its not possible.so we are really nervous because we are living outside Canada and it took a long time to send it.
