Health Canada is investigating the deaths of two people in recent months who donated plasma at private collection centres in Winnipeg.
It says the deaths happened in October and January following plasma donations at two locations run by Grifols, a company that pays donors.
The story was first reported by CBC, which said one of the donors died when her heart stopped while giving plasma.
Health Canada says the investigation is ongoing and no link has been established between the donation process and the two deaths.
Grifols says, based on information so far, it has no reason to believe there was a correlation between the deaths and plasma donation.
The company says it followed protocols in both cases and is conducting its own review in addition to supporting the government investigation.
"Every donor undergoes an extensive health history evaluation and physical examination before being deemed eligible to donate," the company said in a written statement this week.
"We strive to operate under strict operational procedures at the highest standard."
