Canada’s health minister says the country’s doctors, nurses and pharmacists face a “daunting prospect†of navigating a new reality around assisted dying beginning Tuesday.

“Effective tomorrow you may be asked to do something that you’ve never been asked to do before, to help people end their lives,†Jane Philpott, a former family doctor, told in Ottawa Monday.

At midnight Monday, Canada’s provisions in the Criminal Code prohibiting doctor-assisted suicide will expire following a Supreme Court ruling in February 2015. The House of Commons has passed Bill C-14 to set regulations around doctor-assisted suicide but that legislation has not yet been approved by the Senate.

Philpott said she is confident the Senate will give its approval, but in the meantime, there is a grey zone for health-care providers.

Medical regulators in each province have issued guidelines for physicians on providing assistance in dying, based on the Supreme Court’s ruling, but Philpott says that’s not enough.

"While I have faith in Canada's health care providers to carry out these responsibilities responsibly and ethically, I believe that regulatory guidance alone is insufficient, given the nature of what you will be asked to do,†she said.

She expects that many doctors, nurses and pharmacists will be reluctant to assist a patient who requests a medically-assisted death.

She said she has witnessed many deaths and “I know the assurances I would want if I was a doctor practising today.â€

Philpott added that there is currently a “patchy approach†to the protection of the most vulnerable and “insufficient clarity†around who should be eligible for physician-assisted suicide.

“In some provinces people under the age of 18 are eligible and in some provinces not,†she later told CTV’s Power Play.

“In some provinces people with mental illness as their sole cause of suffering are eligible and in some provinces not,†she added.

“Some provinces require two people to witness the signature of the patient and in some cases there is no requirement for a witness,†she went on.

“This is a big concern for me.â€

The Senate is expected to hear today from a constitutional expert who will say C-14 does not comply with the Supreme Court ruling because it restricts access to people who are already near death.

Advocacy group Dying with Dignity Canada is urging the Senate to overhaul the bill, arguing it doesn’t conform to the Supreme Court decision or the Canadian Charter of Rights and Freedoms.

“By limiting eligibility for assisted dying to individuals at end of life, Bill C-14 will deny Canadians who are suffering intolerably from severe chronic illnesses such as ALS and multiple sclerosis — but whose deaths are not imminent — their right to die in peace with the help of a physician,†the group said in a press release Monday. “In addition, the proposed ban on advance requests for assisted dying will effectively exclude individuals diagnosed with capacity-eroding conditions such as Alzheimer’s and Huntington’s disease.â€

Lee Carter, one of the plaintiffs in the landmark case that led to the Supreme Court’s ruling, also spoke out against the proposed bill, saying it traps those suffering from grievous and debilitating medical conditions.

“Today, we’re celebrating that Canadian law now allows Canadians to have a dignified and peaceful death. But on the other hand I feel betrayed. The Liberal government has crafted Bill C-14 to be so restrictive that my own mother would be turned away. People who suffer from Huntington’s disease, MS, or even spinal stenosis, my mother’s condition, would all be denied because they are not ‘terminal.’â€

Philpott told Power Play that she believes “people like Kay Carter and others in similar circumstances would, in fact, be able to access medical assistance in dying under our legislation.â€
