Immigration

Where this offence sits under IRPA

Mischief is hybrid. Mischief over $5,000 has a top sentence of 10 years. That makes a conviction serious criminality under IRPA s.36(1). At $5,000 or less, it creates inadmissibility under s.36(2) (foreign nationals only). Some versions do not depend on value. Mischief that causes actual danger to life can bring a life sentence (s.430(2)). Hate-motivated mischief to a place of worship or a listed community building carries 10 years at any value (s.430(4.1)). So does mischief to a war memorial or to computer data (s.430(4.11) and (5)). Those are serious criminality too. A conviction for damaging property affects immigration status.

This is how the law sorts the offence, not a reading of any one record. An officer decides each case.
