Excerpt from actual CIC letter I received:
Police Clearance Certificate(s): From each country where anyone in the following list has
resided for six months or longer since the age of 18:
the principal applicant
spouse or common-law partner (whether they are accompanying or not)
each dependent child over the age of 18 years (whether they are accompanying or
not)
The Police Clearance Certificate from the country where you are currently residing must
be no more than 12 months old. The Police Clearance Certificate from any country
where you no longer reside must be issued after your departure from that country or no
more than six months before your departure.
Hope that clears your doubt.
