As I shared you the link previously i.e http://www.cic.gc.ca/english/information/security/police-cert/intro.asp .....it is said:
Who needs a police certificate?
In general, you and everyone in your family who is 18 years of age or over need to obtain a police certificate. You must obtain a police certificate from each country or territory where you have lived for six consecutive months or longer since reaching the age of 18. If you lived more than or equal to 180 days, you must submit PCC from there. Your Schedule A_Background decla IMM5669E form, and in section 8, hope you showed your personal history as you spent 1 year in another country also
BTW, if it is in a same country but different state, no need to send another PCC. I guess you say different state means different country.
