It's by-and-largely Australia that fills up my news feed with stories of preposterously large nuggets, and so it's good to hear that there's still a few good sized ones being found on this continent:

Link: The Boot of Cortez, the largest nugget (still in existence) - 389.4 Troy Oz,  found in the North Western Hemisphere, just a few scant miles south of the US US/Mexican border.

There are, upon searching, a surprising number of others that have been found, ranging from California to Nevada and all the way up...

The problem with Canada, of course, is glaciation, which leaves many of the best finds buried under hundreds of meters of overburden.

But the deserts of California, Nevada, Arizona and Mexico are a good training ground before heading to Australia.
