The recent Ontario Court of Justice appeal decision in R v AJL Janssen Landscaping Ltd, 2016 ONCJ 496, has offered some guidance as to when a field may be a “pit” under section 1(1) of the Aggregate Resources Act. Following the decision, a field that is being rehabilitated to accommodate farming uses is generally a “pit” and subject to the ARA’s permitting scheme. But when the primary purpose of that work is to build a structure, it may be exempt.
