Well, there are insufficient numbers of workers. We know of a report that was done by BuildForce Canada that said in our sector alone, achieving the goals that were set out for housing growth and the electrification of heating systems would require—I forget the number in relation to construction workers, but in our sector alone—a quadrupling of registered licensed refrigeration mechanics within 10 years. That's a pretty significant leap, one that the apprenticeship system today cannot deliver, even under the best scenarios.
We have to find ways to re-skill existing workers coming from other sectors. That alone is a barrier to growth. Especially when growth is also tied to policy goals like electrification, it creates a significant challenge.
