Heard from many people residing in Canada that there is a trend of Nepalese immigrants moving from these cities to Calgary, as Himalaya also mentioned above. Toronto is okay in terms of job opportunities and Nepali communiy, although not as good as Calgary is, but life is difficult in Montreal since you have to communicate in French most of the time, road signals, food items, everything is printed in French. So think againif you have planned to land on one of these cities.
