I too am in Victoria. I used to be a hiring manager and had people turn down 6 figure (CAD) offers due to receiving a better one. Although there is admittedly a huge gap between the local companies, and the satellite offices of American companies. Look at KIXEYE, Change.org, Workday, Abe Books (Amazon subsidiary). They typically pay up to 50% more than the local companies, but also typically have higher expectations around skills and availability.
