Ontario’s premier says it’s unacceptable that more than 11-hundred cancer patients were given diluted chemotherapy drugs.

Kathleen Wynne says an independent investigator will try to determine if the problem is systemic, an isolated incident, or if the privatization of drug preparation played a role.

Many hospitals mix the medications themselves, but four hospitals in Ontario and one in New Brunswick all used the same Hamilton, Ontario-based supplier to prepare the chemo drugs.

The hospitals, Health Canada, the provincial governments, Cancer Care Ontario and the Ontario College of Pharmacists are all conducting their own probes into the incident.

Meanwhile -plans for a lawsuit are in the works.

Three firms have announced they hope to launch actions  on behalf of the families of the more than 11-hundred people affected.

They plan to sue the company that prepared the I-V bags containing the diluted medications.

Matt Baer is a lawyer heading up the class-action.

He says the aim of the lawsuit is to compensate patients for any damage they might have experienced to their health, as well as for emotional distress.
