of both countries in the investigation, prosecution and suppression
of crime through co-operation and mutual assistance in criminal
matters, have agreed as follows:
ARTICLE I
Scope of the Treaty
1. The Parties shall co-operate with each other by
taking all appropriate measures that they have legal authority to
take, in order to provide mutual assistance in criminal matters, in
accordance with the terms of this Treaty and subject to the
limitations of their respective domestic legal provisions. Such
assistance shall deal with the prevention, investigation and
prosecution of offences or any other criminal proceedings arising
from acts which are within the competence or jurisdiction of the
Requesting Party at the time the assistance is requested, and in
connection with ancillary proceedings of any other kind related to
the criminal matters in question.
2. This Treaty does not empower one Party's
authorities to undertake, in the territorial jurisdiction of the
other, the exercise and performance of the functions or authority
exclusively entrusted to the authorities of the other Party by its
national laws or regulations.
3. Criminal matters for the purpose of paragraph 1
mean, for Canada, investigations or proceedings relating to any
offence created by a law of Parliament or by the legislature of a
province and, for the United Mexican States, investigations or
proceedings relating to any offence under federal or state law.
4. Criminal matters shall also include
investigations or proceedings relating to offences concerning
taxation, duties, customs and international transfer of capital or
payments.

persons;
(b) provision of information, documents and other records,
including extracts from criminal records;
(c) location of persons and objects, including their
identification;

(e) delivery of property, including lending of exhibits;
(f) making detained persons and others available to give
evidence or assist investigations;

attendance of persons; and
(h) other assistance consistent with the objects of this Treaty,
which is not inconsistent with the law of the Requested Party.
ARTICLE II
Refusal or Postponement of Assistance
1. Assistance may be refused if, in the opinion of
the Requested Party:
(a) the execution of the request would impair its sovereignty,
security, public order or similar essential public interest,
prejudice the safety of any person or be unreasonable on other
grounds;
(b) the execution of the request would require the Requested
Party to exceed its legal authority or would otherwise be
prohibited by the legal provision in force in the Requested Party,
in which case the Co-ordinating Authorities referred to in Article
XII of this Treaty shall consult with each other to identify lawful
means for securing assistance; or
(c) there is a possibility of the death penalty being imposed or
executed in the proceedings in respect of which assistance is
sought.
2. Assistance may be postponed by the Request Party
on the ground that the immediate granting of the assistance may
interfere with an ongoing investigation or proceeding.
3. Before refusing to grant a request for assistance
or before postponing the grant of such assistance, the Requested
Party shall consider whether assistance may be granted subject to
such conditions as it deems necessary. If the Requesting Party
accepts assistance subject to these conditions, it shall comply
with them.
