You are unable to put any RRSP's in your husband's name or profile, regardless of how much room he has available. Whether you contribute to your own RRSP, a spousal RRSP or both, you cannot put in more than your own contribution limit. Your spouse’s contribution limit is not affected by a spousal RRSP.

You must have an official receipt that names you as the "Contributor" and your spouse as the "Annuitant". All contributions are entered on the Contributor's tax return and are limited to and reduce the Contributor's limit.
