From the Boston Globe:
Pfizer targets Canadian pipeline
Pfizer Inc. is escalating its fight against the cross-border Canadian drug trade, cutting off the supply of such popular prescription medicines as Lipitor and Celebrex to two Canadian wholesalers that it suspects are feeding a distribution chain for American consumers.

The two pharmacy wholesalers -- of about 20 wholesalers in Canada -- are based in Manitoba and Alberta, provinces with scores of Internet mail-order pharmacies that have sprung up in response to demand for lower-cost drugs in the United States. Pfizer's move struck home, according to a representative of the Canadian Internet pharmacy industry, who sent out an urgent e-mail alert Thursday to members.

Pawlenty promises to battle Pfizer over plan
Gov. Tim Pawlenty intends to ask the state's pension fund to lead an effort to persuade drug giant Pfizer Inc. not to cut off supplies to Canadian pharmacies that allegedly sell to Americans.

On Thursday the company began shutting off shipments to two wholesalers that allegedly supplied medicine to pharmacies that sold to Americans. Last month, Minnesota became the first state to operate a Web site that helps residents import medications from Canada.
