@ Visaworld...
make a demand draft of Rs.42880/- in favour of "Canadian High commission", payable at New Delhi...
this fees include fees for you and for your spouse, as your kids are below 21 age, you dont have to pay anything for them...
dont get into conversion n all those stuffs, go ahead with the INR currency and make the DEMAND DRAFT OF Rs.42880/-
hope information is clear and loud...
