Monster, degree in hospitality management and Canadian passport will not help you much on that particular position. I have a feeling that you should have opted for other position, where citizenship matters.

I am Croatian, who was working for $1.750 the same job as my Canadian roomate, who was getting paid $3.000.

You have chosen pretty hard job indeed,  and "entry level", one that everybody can get with a 5 days course.

Sure, you will get time off, lots of it if you want, cause you can let someone else do the breakfast service for example, but then that someone else will get yours 50-60$. It can be arranged.
However ... Canadian citizen as Assistant Waiter ... 

WOW hvala na brzom odgovoru sefe . Nisam znao da su tolike razlike u placi ako su ljudi drugih nacionalnosti! Ja sam ceo zivot proveo u restoranima kao kuvar i waiter u malim restoranima nikada 5 zvezdica. i zato se i skolovao za restoran managment. Hteo sam da radim na brodu kao restaurant manager jednog dana. Dali znas koliko brzo se dolazi do takvih pozicija? Takodje sam primetio da u restoranu na brodu se zaradjuje najbolje. Ja sam se nedavno vratio iz kanade (gde sam ziveo 8 godina) u srbiju i aplcirao sam za poslove preko employment power u zagrebu.Oni su pogledali moj CV i rekli da je restoran jedina opcija. Interview je proso bezbolno, cak nismo ni pricali o hrani. Ako mi mozes reci koja su to radna mesta za "Canadian citizens" ako assistant waiter nisu . Hvala unapred
