Bill C-14, the controversial legislation on assisted dying, is now off to the Senate.
The House of Commons has voted 186-to-137 in favour of the Liberals' bill.
But it's expected many senators are pushing for amendments.
Conservative Senate leader Claude Carignan says the bill will not likely be put to a final vote until the end of next week at the earliest.
That means the bill is not likely to be passed by Monday, when the ban on medically assisted dying is formally lifted.
Bruce Grey Owen Sound Conservative MP Larry Miller voted against the bill.
Miller cited overwhelming opposition as expressed by his constituents as the primary factor for his vote.
He says the Liberals legislation lacks safeguards for vulnerable people, including children and those suffering with their mental health.
Miller says the conscience rights of physicians and healthcare providers aren't guaranteed in the bill either.
Miller feels the legislation is "dead in the water " and will never come to pass in its current state.
