Around the Provinces: How Late Is Too Late for an OHS Prosecution to Begin?

We all know that the wheels of justice move slowly, but there are limits to how long the government can take to start a prosecution against you for an OHS violation. The deadline varies by jurisdiction and is based on 2 factors:

  • The length of the so-called limitations period (which is 2 years in all but 4 jurisdictions); and
  • When the clock starts to run’from the date the offence allegedly took place v. from the date the offence first came to the government’s attention.

Needless to say, the “first came to the government’s attention” standard (which is followed in NB, NL, NS, ON and PEI) is not only vaguer but also potentially much longer than a straight calendar count.
