My understanding is that General Stream applicants are not considered as priority and as such not expected to apply through the online portal. You have to file a paper application to be hand delivered to MPNP office in Winnipeg. For those that have applied as General stream applicant please correct me if am wrong.
For the issue of settlement plan, really cannot comment on it as am not too conversant with the form. Just chill out someone in the forum will help with that.
If applying for nomination, you can send thru online:
