Older Release Notes



COPS Projection Adjustment Bug

We found and fixed a small bug in our COPS projection adjustment that caused our adjusted projections to be up to 6% higher than COPS projections in the final projection year. Emsi now matches projection trends from COPS.

Use Beginning-of-Year Minimum Wage

Provinces and Territories sometimes increase their minimum wage multiple times per year. Emsi has switched from using end-of-year to beginning-of-year minimum wage laws as the wage floor for each year’s occupational earnings.

Correct CIP Code Titles

We fixed the titles of the following CIP codes:

CIP 11: changed from “Communications technologies/technicians and support services” to “Computer and information sciences and support services”

CIP 26: English title changed from “Sciences biologiques et biomédicales” to “Biological and biomedical sciences”

Industry Earnings Estimation

We updated our earnings estimation methodology for SEPH, generally making earnings per job more reasonable for Canadian industry data. Earnings did not change significantly.

Industry Unemployment Data

We added unemployment data by 2-digit NAICS, from the Labour Force Survey. This data will be available in the 2020.1 and following dataruns. It can be found in the columns options in the Industry Table. For more information on digit level available, see this article.



None. There were no classification updates or major methodology changes.



Emsi Industry Classification (Emsi NAICS) 2017

Emsi’s industry classification has been updated to closely match the NAICS Canada 2017 version 3.0 classification, which includes the following new industry codes:

  • 111412 – Cannabis grown under cover
  • 111995 – Cannabis grown in open fields
  • 3123 and 312310 – Cannabis product manufacturing
  • 4134 and 413410 – Cannabis merchant wholesalers
  • 453993 – Cannabis stores

For more information on the changes between NAICS 2017 v2 and NAICS 2017 v3, see StatCan’s mapping between them.

While SEPH now covers Cannabis, employment in industries 3123 and 4134 are usually suppressed. SEPH also now suppresses employment in the sibling industries of 3122 – Tobacco manufacturing and 4133 – Cigarette and tobacco product merchant wholesalers. To help unsuppress these values, we estimate employment using Canadian Business Counts (the only other data source we use that covers the cannabis industries) and use those estimates as seed values in our unsuppression.



Standard Geographical Classification (SGC) 2016

Emsi’s geography classification has been updated to match the geography classification used by the 2016 Census. For more information, see StatCan’s writeup.

Emsi Industry Classification (Emsi NAICS) 2017

Emsi’s industry classification has been updated to closely match NAICS Canada 2017 version 2.0 classification. As with Emsi NAICS 2012, Emsi NAICS 2017 combines or omits a few of the standard NAICS codes:



Description NAICS 2017 Emsi NAICS 2017
Farming and Agriculture 111* – 112* 1110
Scenic and Sightseeing Transportation, Other 4879 Rolled into 4871 and 4872
Other Federal Services 9112, 9113, 9114, 9119 Rolled into 9112
Provincial and Territorial Public Administration 912* 9120
Local, Municipal, and Regional Public Administration 913* 9130
International Public Administration 9191 Not Included


For more information on the changes between NAICS 2012 and NAICS 2017 v2, see StatCan’s Revision of NAICS Canada for 2017 (Version 1.0) and NAICS Canada 2017 Version 2.0.

National Occupational Classification (NOC) 2016 Version 1.1

Emsi’s occupation classification has been updated to match NOC 2016 version 1.1. The structure of NOC 2016 Version 1.1 remains unchanged from that of NOC 2011. No major groups, minor groups or unit groups have been added, deleted or combined, though some groups have new names or updated content. For more information, see StatCan’s summary of the changes.

LFS Volatility Adjustment

Due to the volatility of historical LFS data, Emsi is now smoothing historical LFS using Kaufman’s Adaptive Moving Average (KAMA). KAMA is based on the Exponential Moving Average (EMA) and is responsive to both trend and volatility. It closely follows employment when volatility is low and smooths out volatility when employment fluctuates dramatically.
