Sadly that is not really true in Canada. Most companies in Canada only really work with a small group of close provinces.

BC/Alberta

Sackatchewan/Manitoba

Ontario/Quebec

Quebec/New Brunswick

Nova Scotia/PEI/NFLD/New Brunswick

etc

The big companies have offices in each, but they'll usually break them down even further into eastern, central, western regions. And they'll largely never talk to eachother.
