The Bloomberg Nanos Canada Confidence Index climbed to 56.6 from 56.2 a week earlier, the second straight increase. The index reached its highest level since October and is poised to finish the year above its 2016 average of 56.1.

Meanwhile, the pocketbook subindex – measuring job security and personal finances – has jumped in the energy-rich Prairie region to 56.1 from 52.5 two weeks earlier. Sentiment is also up in British Columbia, where the Kinder Morgan project reaches the Pacific Coast.
