OTTAWA — Nearly six weeks after a pregnant Canadian woman was declared brain-dead, she remains on life support in Victoria, British Columbia, because of her family’s hope that her fetus will mature enough to be delivered. The decision by Robyn Benson’s family to try to deliver her child has drawn growing attention in Canada, largely because of a series of moving blog posts by her husband, Dylan Benson.

While Ms. Benson’s situation is unusual, it is not unique. Its circumstances, however, differ significantly from the recent case of Marlise Munoz, a Texas woman whose family successfully sought a court order to end life support intended to bring a child to delivery. Mr. Benson supports the efforts to sustain his wife’s body, and unlike the Texas case, it appears that the fetus in Canada remains healthy and growing.

Mr. Benson, who according to Canadian news reports works in information technology, began blogging about his wife’s death as part of an effort to raise money to care for the baby and to extend his work leave beyond the 35 weeks of partial pay that Canada provides to fathers.

“My wife is dying,” Mr. Benson, who did not respond to an interview request, wrote in a post dated Dec. 29. “Yesterday morning she was complaining of a headache and asked me to go to the store to get some Tylenol for her, and when I came back she was unconscious on the bathroom floor.”
