      Re:      Sun Life Financial, Inc.
       Form 40-F for Fiscal Year Ended December 31, 2004
	            File No. 001-15014

Dear Mr. Stewart:

      We have limited our review of your filing to those issues
addressed in our comments.  In our comments, we ask you to provide
us
with information so we may better understand your disclosure.
After
reviewing this information, we may raise additional comments.

	Please understand that the purpose of our review process is
to
assist you in your compliance with the applicable disclosure
requirements and to enhance the overall disclosure in your filing.
We look forward to working with you in these respects.  We welcome
any questions you may have about our comments or any other aspect
of
our review.  Feel free to call us at the telephone numbers listed
at
the end of this letter.

Managements` Discussion and Analysis

Reconciliation of Operating Earnings, page 10

1.         We note your disclosure of "operating earnings," a non-
GAAP measure, which appears to exclude recurring items, such as
provisions for MFS regulatory settlements. These charges have
occurred in prior periods and absent disclosure elsewhere in your
filing may reoccur in future periods. Elimination of these items
from
the most comparable GAAP measure appears to have the effect of
smoothing earnings.  While the acceptability of a non-GAAP
financial
measure that eliminates recurring items from the most comparable
GAAP
measure depends on all facts and circumstances, we do not believe
that a non-GAAP measure that has the effect of smoothing earnings
is
appropriate.

Exclusion of these amounts raises significant concern about
management`s assertions as to the usefulness of these measures for
investors and the appropriateness of its presentation in
accordance
with Item 10 of Regulation S-K.  Please refer to "Frequently Asked
Questions Regarding the Use of Non-GAAP Financial Measures" on our
website at www.sec.gov/divisions/corpfin/faqs/nongaapfaq.htm that
we
issued on June 13, 2003.  Please tell us how your disclosure
complies
with Item 10 of Regulation S-K for each non-GAAP financial measure
used within your filing.

Contractual Obligations, page 45

2. We note that you have not included all estimated payments
associated with your actuarial liabilities and other policy
liabilities in the contractual obligations table, and it would
appear
that these liabilities represent future legal obligations of the
Company. Due to the significance of these future legal
obligations,
we believe that inclusion of all reserves in the contractual
obligations table will allow investors to more fully evaluate your
liquidity and capital resources. The purpose of Financial
Reporting
Release 67 is to obtain enhanced disclosure concerning a
registrant`s
contractual payment obligations and the exclusion of ordinary
course
items is inconsistent with the objective of the Item 303(a)(5) of
Regulation S-K.  Please revise your contractual obligations table
to
include all expected payments associated with your insurance
liabilities or explain to us how your disclosure complies with
Item
303(a)(5) of Regulation S-K.
