Since July 2015, the Consulate General in Toronto ist the only German mission in Canada to offer comprehensive consular services.

The Consulate General in Montreal has ceased to offer consular services altogether. For any consular matters, please contact the German Consulate General in Toronto
There is one exception. For Schengen visa (short term visa, e.g. for tourist, business affairs) please refer to the Austrian Embassy in Ottawa

From November 2017, employees of the Consulate General in Toronto will offer, about four times a year, limited consular services for German citizens in the premises of the Consulate General in Montreal
