Trade data for sub-provincial geographies

Question

A faculty member here is interested in obtaining international trade flows for South-Western Ontario - does Statistics Canada have these data, and
could a custom tabulation be prepared from them? If not at Statistics Canada, would the CRA collect these (thinking that they might at least have
value of imports by destination and/or exports by origin)? I didn't find sub-provincial geography for trade at Industry Canada either.

I was hoping that the Economic Region would be a sub-provincial level at which data on trade MIGHT be collected.

Answer

Here is the answer we obtained from our contacts in the International Trade Division:

"Unfortunately, trade data by region (i.e., southwestern Ontario) are not available. The lowest level of geography we can provide is Province of
Origin (exports) or Province of Destination (imports). However, custom tabulations could be extracted by Port of Entry/Port of Clearance for the
province of Ontario."

A custom tabulation could be requested if this would be of interest.
