Background: 一個曾經治療過北美洲多名職業運動員的加拿大醫生被懷疑在加拿大和美國邊境給體育運動員提供了興奮劑藥品。警方在對他的診所進行搜查後決定對他進行指控。
The laying of formal charges against Dr Anthony Galea follows three days of rumour and speculation.
He faces three charges of importing, exporting and selling an unapproved drug.
The Toronto-based sports doctor has treated hundreds of professional and amateur athletes.
The police investigation began in September when Dr Galea's assistant was stopped at the Canada-US border and, after a search, found to have human growth hormone and the drug Actovegin.
Dr Galea's Toronto clinic was subsequently raided by police.
Prepared from purified calf's blood, Actovegin is used by some athletes to speed up their recovery from injury.
Dr Galea also faces a separate criminal investigation by the FBI in the United States, where using, selling or importing Actovegin is illegal.
His Canadian lawyer denies that his client has done anything wrong and says that he expects him to be fully vindicated.
One of the doctor's clients, the Canadian Olympic runner Donovan Bailey, has publicly defended him and some of his controversial treatments.
