The women moved to Syria in recent years to become so-called ISIS brides, women married to jihadi fighters whose goal is to raise a new generation of ISIS-supporting children.
On Sunday, a woman only identified as Amy spoke to CTV about moving to Syria from Canada with her ISIS-supporting husband, and her desire to return home to Alberta.
Here is each woman's story.
Shamima Begum fled London for Syria when she was 15 years old.

Shamima Begum and her classmates, Amira Abase and Kadiza Sultana, fled East London in February 2015 to join classmate Sharmeena Begum in Syria, where they were all married off to non-British ISIS fighters, according to The Times of London .
Shamima Begum married a Dutch ISIS fighter named Yago Riedijk. They had two children together during their time in the so-called caliphate, but both died due to illness.
Begum told the Times of London she wants to return to the UK to protect her newborn son, and because she believed ISIS "might not survive after all."
Hoda Muthanaurged people to drive pick-up trucks into crowds on Veterans Day.
Muthana then started a popular Twitter account, where she made violent calls to action from Syria.
One tweet read: "Go on drive bys, and spill all of their blood, or rent a big truck and drive all over them. Veterans, Patriots, Memorial, etc day Kill them."
First she married Australian jihadist Suhan Rahman, who was killed in March 2015. She then married a Tunisian ISIS member, who fathered her son before being killed in Mosul. In 2018, she married a Syrian fighter.
Muthana was captured by Kurdish fighters in January 2019, and is now living in the al-Hawl refugee camp.
She told The Guardian that she wants to return to the US, and claims she was "brainwashed" and regrets her actions.
"We were basically in the time of ignorance [] and then became jihadi, if you like to describe it that way. I thought I was doing things correctly for the sake of God," she said. "I look back now and I think I was very arrogant. Now I'm worried about my son's future. In the end I didn't have many friends left, because the more I talked about the oppression of ISIS the more I lost friends."
Amy fled Canada with her ISIS-supporting husband. Once in Syria, he was killed.
Identified only as Amy, the 34-year-old woman said she wanted to return to Canada.
Amy said she had converted to Islam after marrying a Muslim man in Canada, and they moved to Syria with their two sons after her husband "started learning about the religion."
Her husband was killed, and Amy then married a Bosnian man. The Bosnian man was killed three months later, and now Amy is pregnant with his child and living in the refugee camp.
She said she wants to return to Canada so her sons can get a "proper education."
"I think I should be allowed to go home," Amy told CTV. "I don't believe I did anything wrong. I didn't kill nobody. I didn't do any harm to anybody."
Two French women who fled to Syria to join ISIS are now trying to return.
They were picked up by US-backed forces and now live in the al-Hawl refugee camp, but France is hesitating to welcome them back.
One of the women is 29 years old and from the Lyon region of France.
The other is in her 30s and has three children. She said that she, her husband, and children fled ISIS earlier this month.
"We didn't agree," with ISIS ideologies, she said. "But we couldn't say anything."
The other woman paid a smuggler $50 so she and her two young boys could escape the ISIS stronghold.
"The ISIS fighters scared us," she told AFP. "They'd say" We'll slit your throats, well rape you.'"
It remains unclear when they fled France for Syria or how long they were with ISIS, but the women said they lived quiet lives and their husbands had civilian jobs.
The younger woman said if she returns to France, she wants to be able to practice Islam and stay with her children.
"They'll rip our kids away from us, put them in homes and foster families," one of the women said. "They'll be separated from each other and grow up (with values) against the education we want to give them."
They said they hope theyll be judged fairly if they are put on trial.
"I hope we'll be judged fairly case by case not for everything the group did," one of the women said.
