I don't know that many Slovaks took this route, but Ancestry.com has finally, at long last, added the fascinating records of Canadian Border Crossings, a.k.a. the St. Alban's List. It was a popular and cheap route to the U.S. from English ports, and used a great deal by Russian Jews many of whom fled first to Britain in the 1880's and '90's. My great-grandfather's family came this way. I had found records for some of them a few years ago at the National Archives in Seattle, and now that it is on line I found my mis-filed great-great-grandfather et al. There are actually two sets of records associated with the border crossings: a sort of passenger manifest, and an inspection card. There is fascinating information on those cards, not all of which is duplicated on the manifests. I thought I found the cards on line in a browseable format but can't find my way back to the link. So if anyone finds them please give me a shout. Meanwhile I'm happy to do some spot searches if anyone thinks they have a missing Slovak who came in via the eastern Canadian border/Great Lakes.
"All creatures are balanced upon the creative word of God,
as if upon a bridge of diamond;
above them is the abyss of divine infinitude,
below them that of their own nothingness."
