Assuming source table is in A2:B10, and
this results part below is set-up in D1:H3
(E1:H1 contains "1st of month" dates,
viz.:1-Oct-2005, 1-Nov-2005 filled across)

Result: oct 05 nov 05 dec 05 jan 06
canada 0 0 0 2
S. America 1* 0 0 0
*corrected typo

Put in E2:

=SUMPRODUCT(($A$2:$A$10=$D2)*
($B$2:$B$10=DATE(YEAR(E$1),MONTH(E$1),1))*
(($B$2:$B$10<DATE(YEAR(E$1),MONTH(E$1)+1,1))))

Copy E2 across to H2, fill down to populate the table
and return the desired results

Adapt to suit ..
