Absolutely positive about the medical exam; CIC says (http://www.cic.gc.ca/english/information/medical/medexams-perm.asp):
"If you apply for permanent residence, you must have an immigration medical exam. Your dependants must also have a medical exam, even if they are not coming with you."
CIC is slightly less clear about the police clearance (http://www.cic.gc.ca/english/information/security/police-cert/intro.asp):
"In general, you and all the people in your family who are 18 or older need to get a police certificate."
Medicals is required for everyone - PA and the dependents
even if they are not accompanying you. If you cannot get the medicals done for a dependent for whatever reason, you must write a letter demonstrating that you have genuinely tried to get the medical test done for them but you weren't able to do so for XX reason. CIC might accept this BUT bear in mind that
you can NEVER ever sponsor that dependent again. However, they can immigrate to Canada on their own merits.
PCCs are also required for all adults on application for all the countries they have stayed for a period of 6 months or more (irrespective of whether the stay was continuous or through multiple trips). I am not very sure about the alternative for this. I will do some research and let you know but I am assuming that there will be a process similar to the alternative to the dependent's medical test.
