legally or say officially... both date of birth are correct. Because in Nepal the DOB written in School Leaving certificate is taken as authentic. Now it been long time... it is beyond correction. So, officially both of us have citizenship and passport issued on that date.
Thanks for suggestion regarding PCC.

Dear
Its very simple (Please dont take it serious)
Write them a cover letter and ask them
If any where in the world has it happened that from same mother two kids could be born within a duration of 3 months. If the candians have experienced thsi miracle then they shall reject your application otherwise they are not DUMBS that they can not understand whats going on? All that matters is how you explain
Hope this helps
