"They do not have to follow the (Supreme Court) decision," Dr. Paul Saba of the Coalition of Physicians told The Catholic Register.
"Otherwise, get rid of Parliament and replace it with the Supreme Court."
Since the announcement of the bill, the legislation has received strong opposition both from the Catholic Church and from secular groups.
In April, Cardinal Thomas Collins of Toronto told CNA that "the fundamental move towards implementing euthanasia or assisted suicide is itself troubling" and that the bill would threaten the vulnerable, hide killing with euphemisms, and threaten the consciences of those who oppose it.
The Canadian Conference of Catholic Bishops have continually voiced their concerns and opposition to the bill, and have urged members of Parliament to vote against it.
Together with The Evangelical Fellowship of Canada, the Bishops have signed a declaration against euthanasia and assisted suicide, saying that such measures "treat the lives of disadvantaged, ill, disabled, or dying persons as less valuable than the lives of others. Such a message does not respect the equal dignity of our vulnerable brothers and sisters."
"It is when we are willing to care for one another under the most dire of circumstances and at the cost of great inconvenience that human dignity and society's fundamental goodness are best expressed and preserved," the declaration states.
The Archdiocese of Edmonton responded to the bill by launching the Every Life Matters campaign, aims to reach those who are vulnerable to self-harm or suicide by telling the stories of people who have learned to live despite pain and suffering.
Doctors, lawyers, and family members of euthanized in Belgium - where euthanasia has been legal since 2002 - partnered with the Euthanasia Prevention Coalition and Dunn Media to produce a series of videos begging the Canadian government to reconsider the bill.
