Prime Minister Justin Trudeau warned about the increasing frequency of extreme weather last spring while he was touring homes in western Quebec damaged by the engorged Ottawa River.

The costs faced by the federal disaster financial assistance program have also soared. Since 2011, the program has spent an average of $360 million a year, three times what the average annual cost was over the previous decade. Most of that is for floods and forest fires.

Adapting the building code to mitigate and adapt to new weather patterns is one of the commitments of the national climate change framework, agreed to by Ottawa and 11 provinces and territories almost a year ago. In the spring budget, Ottawa set aside $40 million over five years for the NRC’s five-year climate-resilient buildings project.

But before the building codes can be adapted, the NRC needs to know what kind of extreme weather to expect.

The tender seeks a consultant to update weather and climate data for 660 locations across the country, including expected temperatures, wind patterns, rain and snow fall, and humidity.

The successful applicant will work with the Meteorological Service of Canada as well as officials from Environment and Climate Change Canada to develop information about the expected impacts from average increases in global temperature from 0.5 degrees Celsius up to a maximum of 5 C.

The earth has already warmed up more than one degree on average compared to preindustrial levels and the Paris climate change accord commits the world to trying to keep it from hitting two degrees by the end of the century.

The new data will be then used for a 2020 update to the national building code and the national highways building code, which are not laws but serve as models for provinces and municipalities.

The tender closes Dec. 11 and the NRC expects work to begin on the project in January.
