The Embassy of Russia will only allow processing of Russian tourist, visit, work and business visas in the proper jurisdiction.
This means that you can only apply at the Russian office responsible for your place of residence.
Effective immediately this also means that even if your TELEX or eLOI states the place of application is Ottawa, but you live in another jurisdiction, you must apply in your proper office.
For Canadians living in Ottawa & NCR (613 & 819), BC, NS, NB, PEI, NFLD, NU, YT, and NWT, the place of application is in Ottawa.
