I just landed on the 15th.
1. Seems like it. Even though my meds should have expired last year in October, but COPR, which I received on the 14th of this month, expires in October this year. I think they got an extension of 1 year on my meds.
2. You can call CIC and book an appointment.
3. For my office in Toronto, the wait time was 4.5 months!!!! so obliviously I just went to the border and did my landing. Took 5 hours all together.
4. One page, 2 copies. They will keep one copy and give you the other.
