* Percentage ownership based on 231,029,240 shares of Issuer Common Stock
outstanding as of February 1, 2006, as provided by the Issuer. The Issuer has
informed The Toronto-Dominion Bank that this is a preliminary number reflecting
the issuance of shares of Issuer Common Stock in connection with the acquisition
by the Issuer of Hudson United Bancorp (described below) and recent share
repurchases by the Issuer, and that such number is subject to change based on
final reconciliations effected in connection with the consummation of such
acquisition and further repurchases.

Item 1. Security and Issuer

      This Amendment No. 4 hereby amends and supplements the statement of
beneficial ownership on Schedule 13D, relating to the common stock, $0.01 par
value per share (the "Issuer Common Stock") of TD Banknorth Inc., a Delaware
corporation (the "Issuer") initially filed on March 9, 2005, as amended by
Amendment No. 1 thereto filed on March 18, 2005, Amendment No. 2 thereto filed
on March 28, 2005, and Amendment No. 3 thereto filed on July 18, 2005 (as
amended, this "Statement"), by the reporting person, The Toronto-Dominion Bank,
a Canadian chartered bank ("TD"), with respect to the items set forth below.

Item 3. Source and Amount of Funds or Other Consideration

      The total consideration paid by TD in connection with the purchase of the
approximately 29.6 million shares of Issuer Common Stock acquired in connection
with the acquisition by the Issuer of Hudson United Bancorp, as described in
Item 4, was approximately $942 million, provided from TD's cash on hand. The
purchases made pursuant to the Issuer's dividend reinvestment program, as
described in Item 4, were made from proceeds from a cash dividend paid by the
Issuer, in accordance with the terms of such program. Any purchases made
pursuant to the open market purchases described in Item 4 will also be funded
from TD's cash on hand.

Item 4. Purpose of Transaction

      Item 4 of the Schedule 13D is hereby amended and supplemented by the
following:

      In accordance with its previously reported plans, on January 31, 2006, TD
purchased 29,625,353 shares of Issuer Common Stock, at a price of $31.79 per
share, in connection with the completion of the Issuer's acquisition of Hudson
United Bancorp. The purchase was made in order to finance the cash portion of
the consideration payable to shareholders of Hudson United Bancorp in connection
with the transaction. In November 2005, TD also acquired 676,056 shares of
Issuer Common Stock pursuant to the Issuer's dividend reinvestment program.
Purchases pursuant to the dividend investment program are effected by the
administrator of the program.

      On February 1, 2006, TD announced its intention to commence open market
purchases of Issuer Common Stock starting on or about February 1, 2006. TD
currently intends to at least maintain its ownership percentage in TD Banknorth
at the level prior to the acquisition of Hudson United or, as market conditions
warrant, to potentially increase this stake. On February 1, 2006, the Issuer
announced that its board of directors had approved repurchases of up to an
additional 2 million shares of Issuer Common Stock in open market transactions
which, when combined with the Issuer's previously announced share purchase
authorization, brings the total number of shares authorized to be repurchased

                                                                     Page 4 of 5

by the Issuer to 10.5 million shares. Any repurchases effected by the Issuer
will increase the percentage of the outstanding shares of Issuer Common Stock
that TD owns.

Item 5. Interest in Securities of the Issuer

      Item 5 of the Schedule 13D is hereby amended and supplemented by the
following:

      (a) (i) As of February 6, 2006, TD was the beneficial owner of 126,406,798
shares of Issuer Common Stock, representing approximately 54.7% of the
outstanding Issuer Common Stock, based on a total of 231,029,240 shares
outstanding as of February 1, 2006, as provided to TD by the Issuer. The Issuer
has informed TD that the information regarding shares outstanding is
preliminary, reflecting the issuance of shares of Issuer Common Stock in
connection with the acquisition by the Issuer of Hudson United Bancorp and
recent share repurchases by the Issuer, and that such number is subject to
change based on final reconciliations effected in connection with the
consummation of such acquisition and further repurchases. If the number of
shares outstanding changes, TD's percentage ownership would be correspondingly
affected.

      Except for Mr. Ryan, Mr. Bennett and Mr. Prezzano, none of the individuals
listed on Schedule I beneficially own any shares of Issuer Common Stock. Mr.
Ryan beneficially owns 996,457 shares of Issuer Common Stock, representing less
than 1% of the outstanding Issuer Common Stock. This number includes 37,992
shares of Issuer Common Stock over which Mr. Ryan has voting power under the
Issuer's 401(k) Plan and Proft Sharing Employee Stock Ownership Plan and options
to purchase 909,455 shares of Issuer Common Stock granted pursuant to the
Issuer's stock option plans which are exercisable within 60 days from the date
hereof. Each of Mr. Bennett and Mr. Prezzano beneficially own 4,335 shares of
Issuer Common Stock, which number includes, in each case, options to purchase
2,000 shares of Issuer Common Stock granted pursuant to the Issuer's stock
option plans which are exercisable within 60 days from the date hereof.

      (c) Except as described in Item 4 above and except for purchases by Mr.
Ryan as described below, neither TD nor, to the best of TD's knowledge, any of
the individuals named in Schedule I hereto, has engaged in any transaction
during the past 60 days in any shares of Issuer Common Stock. Mr. Ryan has made
the following purchases of Issuer Common Stock under the Issuer's 401(k) Plan
and Profit Sharing Employee Stock Ownership Plan in the past 60 days: 127.938
shares at $29.68 per share on December 8, 2005; 0.979 shares at $29.70 per share
on December 29, 2005; 177.666 shares at $29.47 per share on January 10, 2006;
0.142 shares at $29.49 per share on January 20, 2006; and 177.438 shares at
$29.53 per share on February 1, 2006.

                                                                     Page 5 of 5

                                    SIGNATURE

      After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.
