Yipes! That would scare me to death tlg!
If that happened to me, I would be on the telephone to all 3 CRA's and be talking to their fraud/identity theft department...have THEM look at the same report as you are while talking to them, and ask THEM how to proceed.
Granted I am an alarmist, but gosh, please take this seriously.
There are others here much wiser than I in this area, and can give you excellent recommendations when they read what you said.
Good luck to you and your hubby.
