We've been given some good advice lately on how to navigate the new
on-line Canadian Passenger Lists. They're indexed not by passenger
name, but by year, ship name, port of departure & arrival, et cetera.
If you don't have at least a year & a ship name, searching for a
relative would be impossible. We've been advised to put in a minimal
amount of information - 1907 - Ottawa (the name of the ship) - which
turned out to be good advice.
So I found the several arrivals of the Ottawa arriving at Montreal
for 1907, and learned quickly that the manifests are alphabetical by
surname. And once I got past the "L" listings (Rachel Liberman), I
went on to another arrival. Until I realized that each manifest
includes maybe 6-10 rolls through the alphabet! And it's relatively slow...
Best of luck,
