5 years to Canadian citizenship is a strong reason to stay. Indians on H1B in the US are looking at about 7-10 years for a Greencard, and then an additional 5 years after that for citizenship.
As a datapoint: I immigrated to the US in 2008. After 5 years on an F1 visa and 10 years on an H1B, I'm still at least 10 more years away from being freed from the immigration and visa hassle.
