I'm looking for the place of work location data for Calgary, 1971 – 2006 at the DA or CT level.
If you are looking for place of work flows that show where the respondents live and then travel to for work then we do have tables such as these but only down to the CSD level of geography (lower levels of geography can be ordered custom):
Commuting Flow Census Subdivisions: Sex (3) for the Employed Labour Force 15 Years and Over Having a Usual Place of Work of Census Subdivisions, Flows Greater than or Equal to 20, 2006 Census - 20% Sample Data
If you are looking for basic place of work data then we do have these CT profiles:
Profile of Labour Market Activity, Industry, Occupation, Education, Language of Work, Place of Work and Mode of Transportation for Census Metropolitan Areas, Tracted Census Agglomerations and Census Tracts, 2006 Census
We do not have any standard product with DA level data. This data would only be available custom through the regions.
