Is this consistent with the B.C.-Alberta Trade, Investment and Labour Mobility Agreement (TILMA)?
Yes, TILMA requires B.C. and Alberta to work towards enhancing environmental protection and health standards. Alberta has been advised of this requirement and does not have a similar requirement, however, environmental and human health measures are legitimate objectives to TILMA. This measure is consistent with the intent of TILMA. Environmental measures need to be genuine to their intent and not impose any competitive advantage to either jurisdiction. Diesel retrofit devices can be purchased in any jurisdiction.
