In Canada is it illegal to record a conversation without consent?

Telephone tapping is officially strictly controlled in many countries to safeguard an individual's privacy; this is the case in all developed democracies. However, in certain jurisdictions such as Germany, courts will accept illegally recorded phone calls without the other party's consent as evidence. In the United States, federal agencies may be authorized to engage in wiretaps by the United States Foreign Intelligence Surveillance Court, a court with secret proceedings, in certain circumstances. Many businesses and other organizations record their telephone calls so that they can prove what was said, train their staff, or monitor performance. This activity may not be considered telephone tapping in some, but not all, jurisdictions because it is done with the knowledge of at least one of the parties to the telephone conversation. It is considered better practice to announce at the beginning of a call that the conversation is being recorded. In India, telephone tapping has to be approved by a designateed authority. It is illegal otherwise.
