That is certainly something we took into consideration in designing the availability standard. For example, we have made sure to include plug-in hybrid vehicles to be considered as zero-emission vehicles under the standard. Plug-in hybrids have both the electric capability as well as traditional gas motors, so they can provide that extra backup that could be required for some Canadians.
Similarly, we see that even though range can be reduced in very cold weather, with the rapid technological improvements that are happening in this technology, that range will only improve. We see very high rates of electric vehicle uptake in other cold countries, such as Norway, where it's currently at 90%. This is another reason the availability standard increases the sales standards over time, recognizing that it will take time for those technological improvements to happen.
