Check you e-mail for any messages from MPNP. Remember to also check your "junk" folder as I have heard about a case where this happened.
If you have not received any e-mail in a weeks time from "status completed" that you application is declined, you could regard your application as successful and you will receive MPNP Certificate within a couple of weeks (this depends on what physical mailing address you asked them to send snail mail).
If anyone here is outside of Canada, remember to change your mailing address to that of your sponsor inside of Canada. This will save time as you supporter can then send it with a courier (fed ex, dhl, etc). The MPNP only uses old conventional snail mail and I have heard of cases where the letter is lost in the post system and then MPNP only re issues it after a couple of months.
For all that still has Status Received / Pending / Process - keep the good faith and know you status will change soon!!!
