Are you Indonesian residing in Canada? If your wife is in Indonesia, then your case will be handled by Singapore through an Outland process. Unless she's with you here in Toronto (she can be, under a temporary visa/TRV, this is what we call dual-intent), then you will be applying Inland.
If I'm understanding you correctly, you want your wife to send her Surat Keterangan Catatan Kepolisian and Medical to be sent to you, whilst you complete the remaining documents; and you will send everything together in a package to CIC-Missisauga? Don't "expect" much from these Visa Offices. The more preparation you do ahead of time, the more likely you will save time. Don't wait for them to request something from you; provide them everything from the get-go!
You should refer to this
thread here. That person should be the example of how every case should be prepped.
