Extradition Lawyer Canada
Canada and the United Kingdom maintain one of the world’s longest-standing extradition relationships. If you are in the UK facing a formal extradition request from Canada — or a UK citizen who has been arrested in Canada on a UK request — specialist legal advice from both jurisdictions is essential from the earliest stage.

The UK–Canada Extradition Treaty
The United Kingdom and Canada are parties to a bilateral extradition treaty originally signed in 1976. Canada is designated as a Category 2 territory under the UK Extradition Act 2003, meaning that extradition requests from Canada are processed under Part 2 of the Act. Part 2 involves a multi-stage procedure: a formal diplomatic request to the Secretary of State (Home Office), consideration by the Secretary of State of whether to issue an authority to proceed, a hearing before Westminster Magistrates’ Court, a further decision by the Secretary of State on surrender, and a right of appeal to the High Court.
The treaty provides for extradition in respect of conduct that constitutes an offence under the laws of both countries — the dual criminality requirement. It also sets out a number of grounds on which extradition may be refused, including where the offence is of a political character, where the person has already been tried for the same conduct, or where extradition would be contrary to humanitarian principles.
The Extradition Process — Step by Step
Step 1: The diplomatic request
Canada submits a formal extradition request to the UK Home Office through diplomatic channels. The request must include the applicable Canadian arrest warrant, a summary of the evidence or the conduct alleged, and the relevant provisions of Canadian law. The Home Office reviews the request to determine whether it meets the formal requirements for an authority to proceed.
Step 2: Authority to proceed
If the Secretary of State is satisfied that the request meets the relevant requirements, they issue an authority to proceed. At this stage the Secretary of State may also refuse to proceed — for example, if the offence is of a political character, if the person has already been tried for the same conduct, or if the death penalty applies in Canada for the offence in question.
Step 3: Extradition hearing
Westminster Magistrates’ Court considers whether the conduct alleged constitutes a criminal offence under UK law, whether any statutory bars to extradition apply, and whether extradition would be compatible with the requested person’s rights under the Human Rights Act 1998. If the judge is satisfied on all these issues, an extradition order is made. The case then returns to the Secretary of State for a final decision on surrender.
Step 4: Appeal
Either party may appeal the extradition order or the discharge of the request to the High Court. Extradition is stayed pending any appeal. The High Court can allow an appeal on the basis of fresh evidence, a question of law or a finding that the decision was wrong. On certified points of law of general public importance, further appeal to the Supreme Court is available.

Common Grounds to Resist Extradition to Canada
While Canada has a well-functioning criminal justice system, there are a number of grounds on which extradition to Canada can be — and has been — successfully resisted in UK proceedings.
Human rights under Article 8 ECHR: The right to respect for private and family life is frequently engaged in UK–Canada cases. Courts weigh the strength of the applicant’s ties to the United Kingdom — including UK citizen children, a long period of lawful residence, employment and property — against the gravity of the offence alleged and the public interest in extradition. These cases turn heavily on their particular facts.
Forum bar: Where a substantial part of the alleged conduct occurred in the UK — for example, in cases of online fraud, money laundering or cybercrime with significant UK elements — the forum bar may be available. The court must weigh a statutory list of factors and consider whether it would be in the interests of justice for proceedings to be brought domestically.
Dual criminality: In cases involving complex financial offences, regulatory offences or specific categories of Canadian criminal law, it may be possible to argue that the alleged conduct does not constitute an extradition offence under UK law.
Passage of time: Canada occasionally issues extradition requests in relation to conduct alleged to have occurred many years — sometimes decades — earlier. Where the delay is not attributable to the requested person, and where extradition would be unjust or oppressive by reason of that delay, the court must discharge the request.
Physical or mental condition: Where the requested person has a serious medical condition that would be significantly aggravated by extradition or by conditions of detention in Canada, this can be a powerful basis for challenge.
Interpol Red Notices Issued by Canada
Where Canada issues an Interpol Red Notice in connection with an extradition request, the person concerned may be arrested in any Interpol member country. A Red Notice does not constitute an arrest warrant and has no direct legal effect in the UK, but it can lead to provisional arrest at the border or following a routine check. If you are subject to a Canadian Red Notice and are currently in the UK, it is important to take legal advice immediately — both in relation to any potential UK extradition proceedings and in relation to challenging the notice through Interpol’s Commission for the Control of Interpol’s Files (CCF).
Our solicitors coordinate Red Notice challenges through the CCF with any parallel UK extradition proceedings. A successful CCF challenge — establishing that the notice was issued in violation of Interpol’s rules — can significantly strengthen the position in UK extradition hearings, though the two processes are independent of one another.
Does the UK extradite to Canada?
Yes. The UK and Canada have a bilateral extradition treaty and an established extradition relationship. Canada is a Category 2 territory under the UK Extradition Act 2003. Requests from Canada are processed through the Home Office and Westminster Magistrates’ Court.
What is the dual criminality test?
Dual criminality requires that the conduct alleged constitutes a criminal offence under the law of England and Wales as well as under Canadian law. If the conduct would not be an offence in the UK, extradition must be refused. This is particularly relevant in cases involving complex financial, regulatory or drug-related offences where the two legal systems may treat the same conduct differently.
Can I resist extradition to Canada on human rights grounds?
Yes, in principle. The most common human rights arguments in UK–Canada cases concern the right to private and family life under Article 8 ECHR — particularly where the person has strong ties to the UK including children, long residence and employment. The strength of any challenge depends on the specific facts of the case and the gravity of the offence alleged.
How long does extradition to Canada take?
From initial arrest to final extradition — including any appeal to the High Court — the process typically takes between one and three years. Particularly complex cases, or those that reach the Supreme Court, can take considerably longer.
Can I get bail while resisting extradition to Canada?
Yes. Bail is available in extradition proceedings at Westminster Magistrates’ Court. The court assesses the risk of absconding and may impose conditions including a curfew, regular reporting, surrender of travel documents and electronic tagging. We advise on prospects of bail at the outset of every case.
