The source's changes are:

• Index base year: From 2007 to 2012
• Scale: From thousands of Canadian dollars (Ths. CAD) to unitary (CAD)
• Frequency: From quarterly to monthly
• Geo coverage: Ottawa-Gatineau (ICAN_MOHL) terminated

In response, we have:

1. Archived predecessors (quarterly, 2007=100, 1997Q1 to 2018Q3) by renaming with an "_07" specifier, marking metadata as "discontinued" and segregating in the catalog.
2. Created replacements (monthly, 2012=100) that start at 2015m1.
3. Created quarterly estimates starting from 1997Q1.

Dataset properties:

• Measurement: Canadian dollars at current prices (CAD) or constant year-2012 prices (2012 CAD)
• Adjustment: Seasonally adjusted (SA)
• Geo coverage: Canada, 12 provinces and territories, 34 census metropolitan areas (CMA), two census agglomerations (CA)
• Native frequency: Monthly
• Start date: 2015m1

The series reside in the historical catalog (Canada » Real Estate » Non-residential » Investment in non-residential structures) and include, for example:

• HSCNR_07AQ.ICAN        = [DISCONTINUED] Real estate: Non-residential investment - Total, (Ths. 2007 CAD, SA)
• HSCINVTNRSAM.ICAN      = Total, (2012 CAD, SA) 
• HSLINVTNRSAM.ICAN_MCAL = Total, (CAD, SA) - for Calgary [CMA]
• HSCINVTIGVAQ.ICAN      = Institutional and governmental, (2012 CAD, SA)

Because catalog locations are subject to change, the upper-right search box on DataBuffet.com provides a "find in catalog" mode that accepts a mnemonic.

Please be aware that

In response to the source's termination of Ottawa-Gatineau (ICAN_MOHL), we report two subregions that can be summed together and used as a replacement.

These two subregions are: Ottawa-Gatineau, Ontario Part (ICAN_OHO) and Ottawa-Gatineau, Quebec Part (ICAN_OHQ).
