While the laws cited are American, the general principles still apply.
The crimlawcanada.com FAQ agrees:
Q: I’ve heard on TV that you should never make a statement to police – but that can’t apply to me. I’m innocent and haven’t done anything wrong. I’m sure if I just answer their questions, this will all go away.
The overriding urge to trust police officers is bred into us as children. When an officer knocks on your door, one often feels a compulsion to just explain the situation confident that the officer is on your side and will help you out.
Nothing could be further from the truth.
If police officers are asking you questions about your involvement in a crime, they are not doing this to help you. They are simply doing their jobs – trying to catch criminals. Every word you say to police officers will be written down in their notebooks and used to try to prove that you committed the crime they think you committed.
If the officer thought you weren’t guilty of anything, he or she wouldn’t be asking you questions.
Every person has the right to remain silent and it is a right that everyone – guilty or innocent – should exercise. If an officer is asking you questions, be firm but respectful and indicate to the officer that you do not wish to answer any questions until you have spoken with your lawyer.
