If you are arrested for or charged with a crime and released, then your release will come with conditions that you must follow. You can be released on an appearance notice, an undertaking, or bail. The conditions you are released on will depend on the charge you are facing and your situation. Breaching a release condition can – and usually does – result in you being sent to jail and picking up another criminal charge.
The Supreme Court of Canada has made it very clear that most people charged with crimes should be released, that they should be released on the least strict form of release that is reasonable, and that the least strict reasonable release conditions should be imposed.
