While Section 10b of the Charter guarantees the right to be provided legal counsel, Canadian law only entitles criminal suspects under the age of 18 to have counsel actually be present throughout the entire interrogation. Once an adult suspect has asserted their right to counsel, the police are obliged to hold off in attempting to obtain evidence until the suspect has had a reasonable opportunity to contact legal counsel, however after that opportunity has been exhausted there is no guarantee of further access until the interrogation is over. Also, in Canada even if the suspect directly asserts his decision to remain silent, the police may continue to interrogate them. There is no automatic exclusion of evidence obtained after such an assertion, however it risks breaching the confessions rule if a court finds that it created reasonable doubt to whether the confession was obtained under "oppressive conditions", a determination which is made upon the totality of evidence.
