I have a student looking at inter-provincial trade - specifically products in the Agrifood Industry. All the Cansim tables that cover this are terminated - the most recent data is 2011 (386-0003).
The same for the Provincial input-output tables (381-0028).
We can't find what these tables have been replaced with - (some point to tables that don't break down by province, others don't break down by industry).
The interprovincial trade flows are now incorporated in the Supply and use Tables (catalogue 15-602-X)
