Maybe someday you can come back and take a work permit in the west and visit this corner too! I'm sure you still got to see many great places in central Canada like Niagara Falls and Algonquin (I have never seen them yet), there is too much to see it all in one visit, it's large territory! Rockies do have seasonal tourism related job availability that mostly employ foreigners, the pay isn't great for Canadian standards and the accommodations directly in the park are expensive but it is possible to stay in near by small towns at a fraction of the cost( within 20 min to half hour drive away). If I was a foreigner, I would still do it, get a paid vacation in such a beautiful place. Hit me up if you ever need tips on what small towns to stay in if you have the opportunity to come back. I hope you enjoyed your Canadian journey!
