Are DNA paternity tests legal in Canada?

In Canada, DNA filiation tests are legal and widely used for personal, medical, or legal purposes. However, it is recommended to consult a legal professional to understand the specific legal implications of your situation.

Please also note that the consent of all participants is required to proceed with a paternity test with Adnà.

Yes, for relationship tests, our partner laboratory can perform the analysis on non-standard samples such as a toothbrush or blood, for example. The cost is higher, ranging from $750 to $850, and the turnaround time is longer because the laboratory first applies a DNA extraction method tailored to the type of material. Some samples (e.g., hair without roots, old tissues, cigarette butts that are too old) contain very little or degraded DNA.
