Canadian Criminal Procedure and Practice/Arrest and Detention/Warrant Arrests

General Principles
A warrant is one among several means of securing an accused's attendance at court. On warrants, the Criminal Code states:

Under s. 511, the execution of a warrant or arrest authorizes 1) the arrest of the accused and 2) the officer to bring the accused before a judge in the territorial division in which the warrant was issued.

Hearsay "tip"
From R. v. Warford: We are concerned instead with a search authorized by warrant on grounds furnished by a ‘coded' informer of known identity and proven reliability. He had provided the officer who swore the information with detailed and specific reasons for believing that evidence of drug trafficking would be found in the respondent’s apartment. The informer had personally seen cocaine in that apartment a few days earlier. He gave the police the full name, approximate age and full address of the respondent, and a description of the respondent’s apartment building and of the location of the respondent’s unit in that building.
 * R. v. Beauregard (1999), 1999 CanLII 13778 (QC CA), 136 C.C.C. (3d) 80 (Que. C.A.), provides an example of a situation where a search was found to be valid based on an assessment of the totality of the evidence. Fish J.A. explained, at page 83:

Feeney Warrant of Arrest
When a suspect is the subject of an arrest warrant and he is believed to be found in a dwelling-house, the peace officer must seek authorization to enter the dwelling using a "feeney warrant".

A person has an increased privacy right in their home which prohibits warrantless entries even for the purpose of a lawful arrest or seizure of evidence.

Section 529 states:

Any power to enter a dwelling-house to carry out an arrest under a criminal code offence will equally apply to warrants under other federal Acts.

Canada-wide Warrant
Canada-wide warrants are warrants that are not attached to particular jurisdictions. It can only be issued by a judge of a superior court and not a provincial court judge.

It is provided for under s. 703:

Transferring Local Warrants to Different Provinces
Where no Canada-wide warrant is issued and a regular 514 warrant has been issued in another jurisdiction, under s. 528 the local court may endorse the foreign warrant:

This section allows either local police or the police of the other jurisdiction to arrest the accused, who is located locally, and be transported to the jurisdiction of the original warrant.

Executing Warrants from Other Provinces
Section 503(3) addresses the situation where an accused is arrested without a warrant outside of the jurisdiction and the local jurisdiction would like to compel their attendance at court.
