Stamp from Canada Post's Millennium Collection souvenier sheet (can-20000117-w-001). According to the Unitrade stamp catalog

The stamp catalogues were not going to recognize the 68 stamps printed in the book because of the "limited edition" and "excessive" surcharge over face value (almost double the price of the stamps). As a result Canada Post re-issued the 68 stamps over a 3 month period in 17 different panes of 4 stamps each.

The stamp in the book (can-19990915-s-003) and stamp in the souvenir sheet were identical except for one minor difference: the size of the microprinting in the upper left corner of the stamp. See the difference in the image to the left.

From the Wikiepedia entry for Lester Pearson

The award for the best National Hockey League player as voted by members of the National Hockey League Players' Association (NHLPA) was known as the Lester B. Pearson Award from its inception in 1971 to 2010, when its name was changed to the Ted Lindsay Award to honour one of the union's pioneers.

Pearson attended Oxford University and while there he played hockey and was even on the Oxford team that won the very first Spengler Cup in 1923. From the Wikiepedia entry on the Oxford University Ice Hockey Club

With the introduction of the Rhodes Scholarship, the top Canadian players at the University of Oxford formed the Oxford Canadians, but after World War I, the University of Oxford team included Rhodes Scholars. Such players included Lester B. Pearson, Roland Michener, George F.G. Stanley, Clarence Campbell, Allan Blakeney, Ronald Martland and Otto Lang. Thus strengthened, it won the Spengler Cup in 1923, 1925 and 1931.
