It's an interesting question. Regardless of whether it's an electric vehicle or an internal combustion vehicle, plastics and chemistries now make up close to 40% of the value of the materials in a car. It's certainly not the weight, but what allows them to be lightweight. It's what allows the battery within the vehicle to operate.
It's important certainly from a Canadian perspective—we have the chemicals management plan and we're assessing chemistries—that we think about where we're bringing goods in from and whether those products are going through the same assessment that happens in a very robust way here in Canada.
