Can you go to jail in Canada for pulling a false fire allarm?

The answer would depend in the Circumstances and Municipal By-Laws (if any) of the area where you committed this action.

In theory, pulling a fire alarm can be interpreted as the following, which can lead you to jail:

* Mischief (Section 430 of the Criminal Code of Canada)

* Disturb of the peace (Section 175(1) of the Criminal Code of Canada)

* False Fire Alarm (Section 437 of the Criminal Code of Canada)

However, many municipalities in Canada have municipal Bylaws against this act, which, in most of the cases, are punishable by a fine.

Once again, it depends of the circumstances. If you were intoxicated while doing so, an Officer might decide to detain you under the Intoxicated Persons Detention Act, which allows a Peace Officer to detain an individual intoxicated in a public place.
