After contacting IRCC I just received an email from Sidney office saying that my application was returned on March 30 because it was incomplete. However I haven't received anything yet (let's see if it comes next week after the long weekend and the ice storm here in QC). It is weird because I triple checked everything to be sure all was there. Furthermore, it is not the same time IRCC sort of screws up our immigration applications (I had to resend the photos twice for the PR Cards, which took more than 8 months)...
In case the application does not arrive back to me, what should I do? Re-send again the whole application with a new signed date? It seems I am not very lucky with IRCC
