Answer

Brief Explanations:

The term "premetric" refers to the time before the adoption of the metric - system in Canada. The reference to "coldness" implies a comparison of temperature measurements before and after the metric - system adoption. So it suggests temperatures were colder before Canada converted to Celsius (a part of the metric system) measurements.

Answer:

temperatures were colder before Canada converted to Celsius measurements
