Library & Archives Canada have a work in progress presently named "Moving Here, Staying Here". The first part of the Moving Here project is scheduled to launch soon. It is a virtual exhibit about immigration to Canada from a government documents perspective, but LAC is adding some databases, too.
The one probably of most interest is the digitization of passenger lists, 1865 to 1922. It will have a searchable searchable database by date, ship and port (but not by passenger name) , with a link to the nominal database of Canadian Passenger Lists for all ports from 1900 - 1924 that the Nanaimo Family History Society is creating.
LAC also will have a nominal database and digitized images for the Montreal Emigrant Society passage book, 1832, the Ward Chipman papers (Loyalist lists), Upper Canada
Naturalization registers and one of the Chinese immigration registers.
LAC also plans a major revision and/or addition to the Home Children database.
