do medical exam in Canada?

I am an employer who want to apply my flipino caregiver from Hong Kong. She has been working for me in HK for 8 yrs. I applied the LMO already, and just waiting for a reply. How long is the processing time?
I have a few questions that need your help!! My caregiver is currently in Canada with me now as a visitor. I know she has to send the application back to CIC in Hong Kong to obtain her working permit, but I want to know if she can do her medical exam in Canada with a designated medical pratitioner listed under the website? Also, can she do her college documents authentication in Canada and where? She can't go back to Philippine within the next few months. Does she have to go thru that POLO thing? Anything we can do in BC ahead of time to expedited her application? Thanks
