The top chart, found in this CIBC report on labour market myths, plots the share of Canadians who have been with their employer 5 years or greater and the bottom chart is Canadian GDP per capita from the St. Louis Fed FRED site. When the percentage of workers at the same employer starts declining and bottoms it appears Canada enters a recession within one year. The peak in this measure seems to happen about 2-3 years before the bottom.
The share of workers with the same employer for 5 years or greater may have peaked in 2015. If this indicator continues to work, the bottom should be sometime in 2017-2018 with a recession beginning in 2018-2019. That seems like a long time off and other indicators would need to confirm it, but my attention is piqued.
