NRCan tabulated the data in five-year increments. I do apologise but, on checking, I found I'd pulled a number from the wrong line into my table as the Canadian consumption in 2020. One day I'll learn that when things don't look right they probably aren't. The revised (and hopefully correct) graph is posted below. Although it appears that consumption has been straight-lined from 2005, there are demand differences in individual sectors. Some go up while a few go down.
