The police must obtain consent or prior judicial authorization in order for evidence of the accused’s DNA to be legally obtained.R. v. Stillman, 1997 CanLII 384 (SCC),  1 S.C.R. 607. continues to govern the procedure for seizing the accused’s own bodily materials. Police may dab or swab an accused’s hands incident to arrest to check for gunshot residue or to obtain a sample of blood visible on the accused’s skin See, for example, R. v. Backhouse (2005), 2005 CanLII 4937 (ON CA), 194 C.C.C. (3d) 1 (Ont. C.A.), at paras. 139-45; R. v. Smyth,  O.J. No. 5527 (QL) (S.C.J.)). Either of these procedures might enable the police to obtain the accused’s DNA, but the police are not entitled to use them for that purpose. Similarly, if an accused’s DNA is obtained through a penile swab and the swab was taken without a warrant authorizing such seizure, or the accused’s consent, the accused’s DNA cannot be used for any purpose.R. v. Saeed,  1 SCR 518, 2016 SCC 24 (CanLII), at para 48.
In R. v. Liew and Yu, 2012 ONSC 1826, the Superior Court of Ontario considered the question of whether an attempt on the part of the police to establish a rapport with the accused on the car ride to the police station breached the accused’s section 10(b) right. The accused had been informed of his right to counsel upon arrest, but had not yet had access to counsel. The Court held that the attempt on the part of the police to establish a rapport with the accused on the car ride to the police station was the initial stage of an interviewing technique employed by police (akin to the Reid Technique, which involves the interviewer establishing a rapport and level of trust with the subject, then confronting the accused about the crime). As such, it breached the obligation on police to "hold off" questioning a detainee until he/she has been given a reasonable opportunity to contact counsel.R. v. Liew and Yu, at para 75.
