Hello Im_ricky !
It can delay your processing approx 6 weeks buddy, its better pay the landing fee immediately & as when you get your PPR, you can attach the receipt to confirm CHC ND that you have already paid. More over it takes around 6 weeks to confirm by CPC-M to CHC ND.
That's what I did by using the client ID of my spouse and payed the fees to CPC-Mississauga. My spouse later got notification via post after two months that they have notified the CHC ND of the PR fee received. I didn't wait for a fee pay request letter, anyhow you have to pay so why unnecessary delay Yaar !
Kind advice say your spouse to pay the fee as early and rest up to u.
