Just posting this for someone who is in the same situation (I was in).
This might not apply to your consulate so don't go by my words, check your consulate first.
I emailed Sydney General Consulate and advised them if it will take long, I would miss out on my training and orientation in Canada and proposed whether I can come to their office and if they can process my application on the same day.
They emailed me back that it might be possible.
I took a chance.
Took a flight to Sydney yesterday night went to the consulate first thing in the morning 9:00 AM showed them the email about 1 day visa processing. They asked due to the documentation I have provided for me and my partner, they needed around 2 and a half hours to verify the documents etc. Went back to their office at 11:15.
11:30 AM receptionist gave us our passports back with visitor visa acceptance.
Regards,
