What the rule actually says

The legal text is short. The provincial statute governing this topic is worth reading in full — most disagreements come from paraphrasing it instead of quoting it. Bookmark the actual government page and refer to it in every notice you send.

The mistake landlords make most often

The most common failure isn't malice — it's process drift. Templates get edited over time, notice periods shift by a few days, and small errors compound. A single quarterly review of your standard documents fixes 80% of the compliance risk.

Bottom line

The landlords who avoid tribunal trouble are the ones who treat compliance as a habit, not an emergency. Fifteen minutes a month keeps you out of the ninety-minute hearing.
