CanED,
I think CIC would probably contact you if they feel they need a more up to date police checks. Mine only were valid for 1 month and then 3 months so both are expired :
johanna125,
did you make copies of the forms you filled out? I know that on one of the forms for the sponsorship it asked about filling in your sponsors email address. If you did this then they would only contact you by email, if not then they would mail you everything. So... first did you fill the email section in? if yes, did you correctly write the email address.
Sorry if you've already provided these answers before...
