Query On Police Report, Visa From Date of Medical

Received a reply 30/12/08 requesting for the following
1) Right of Permanent Resident Fee (RPRF)
2) Medical Exam
3) Police Report from IRELAND
I am required to submit these details within 90 days.
The medical was done in the UK 05/01/09.

1) I am trying to get the Police report from Ireland but have been told it takes 8WKS. I just called the Irish for the police report after 3WKS they say the person handling it is off sick. I am concerned that it may not just come before the 90 days.

As the medical is already done, can I just submit the application fee of $490.00 and when I get the police report I forward it to the Canadian embassy.

2) Also is it true that the visa starts from the time you do the medical.
"the expiry date is one year from the time medical examinations were completed."

"You must land in Canada before the expiry date, which appears on your Canada Immigration Visa.
Usually, the expiry date is one year from the time medical examinations were completed. As this is not always the case, be sure to verify the expiry date as soon as you receive your Canada Immigration Visa."

Any response would be highly appreciated.
