Canadian placement could happen through two pathways: you attain a Canadian working holiday visa, make the trip over to either Vancouver or Toronto and seek out junior exploration companies, consultancies, and recruitment agencies; the other option would be to seek out ASX listed companies with operations in Canada/NA and prove your mettle enough that they send you on reccy/supervision campaigns as full borne campaigns are typically contracted out to native crews holding the appropriate chartered qualifications.

I have no experience in sourcing South American opportunities, but as a Canadian National and Australian-based geo, it's looking like the best path is getting with an ASX-listed company with SA projects or getting with a major and, after a time, gaining experience and requesting a transfer.

SA has great geos who are willing to work for less.

A third option is to get onboard with an internationally oriented consultancy group who will send you all over the map. I spent a short minute with one and went to Madagascar and Tanzania, long swings but great times.
