In Ontario, you need the document mailed to you from the dmv. They dont accept the print outs given by the local office or from online. They are adamant in not accepting even if you show the driver license, seems that they think that all are fake. So dont take chances, you will have to get the document mailed from dmv head office hence request soon and get it while moving.
So use the form
https://www.dmv.ca.gov/portal/dmv/detail/online/dr/welcome INF1125 (PDF). Possibly get the certified one(seems no charge).
This should have the date issued and expiry.
FYI - I moved from MI, not from CA.
