In a quiet, leafy suburb of Toronto, a 30-year-old Afghan woman spends most afternoons on the phone, hoping she can reach her two younger siblings and father.

They are not in Afghanistan, but instead just miles away, across the border in the US, held in Immigration and Customs Enforcement (ICE) detention.

The three have been there in crowded cells for months, stuck in what their lawyers say is a bureaucratic limbo between Canada and the US.

They are eligible for asylum in Canada because they have immediate relatives who are legal refugees in the country, but can only file their claim at the land border - and US officials insist that they will only be released if they enter Canada by air, which they can't do without a visa, their US lawyer told the BBC.

That visa application is currently under review and they remain stuck, currently unable to make a claim in Canada and facing deportation from the US.
