A judge in the US has ordered that former media tycoon Conrad Black must stay in the US until his next court hearing in August.
The judge in Chicago said she needed more information on Mr Black's financial situation before she could rule.
Conrad Black was released from prison in Florida on Wednesday after serving more than two years.
He was freed on a $2m bond pending an appeal against a conviction for fraud and obstructing the course of justice.
On Thursday, in his first public appearance since being allowed out of prison on bail, Conrad Black said he wanted to go to Toronto, where he owns a mansion in an upscale neighbourhood.
But US District Court Judge Amy St Eve said he will have to stay in the US at least for now.
The judge gave Black and his lawyer a couple of weeks to provide a full financial picture, which she will then use to evaluate his flight risk.
However, it is unclear whether Canadian-born Black would be welcomed or even allowed to enter Canada.
He is a convicted felon and is no longer a Canadian citizen.
In 2001, he clashed with Jean Chretien, a former prime minister and long-time political foe, over Black being honoured with a British peerage.
Mr Chretien blocked the appointment to the House of Lords, saying it was British interference in Canadian affairs. Black subsequently sued, but he lost the case.
Black then renounced his Canadian citizenship in order to be able to take his seat in the House of Lords.
He would now need a special ministerial permit to return to Canada, where the immigration minister has so far refused comment.
