If you’re dealing with members of Canada Deposit Insurance Corp., consider putting somewhat less than $100,000 in one account and the rest in another.

I thought the insurance was per institution per "person" (your RRSP is a separate "person"). Simply having 2 accounts under the same name might not protect you.

Also, you may want to avoid certain shaky institutions. You don't want to have your money tied up in CDIC processes when you happen to need it.
