TVR is fairly easy to get, at least that's from my experiences (though not personal. Friends are a couple, husband is currently studying in Toronto, while the wife is in Jakarta. She requested an Open Work Permit, and if I understand her correctly, the embassy gave her the work permit she needed. Please don't quote me on that. I'm a PR myself, so, I'm not that familiar with visa applications.
I'd wait if I were you. In case you're requested for an interview, Canada and Singapore is a LONG way to go.
