We don't enjoy the same benefits. We cannot access social security, if we choose to continue our education, we will have to pay international student fees. We can only buy a house if we put down 35% of the value and we are not eligible for any programs like first time home buyers discounts. Most people don't have that kind of money. We have to periodically renew our work permits and all IDs after that's done.
Finally, some people like me are separated from their families and the only chance for reunification is a PR. My husband was denied a visitor visa and a spousal work permit. If I were a PR I could sponsor him, but having a work permit I could only add him as my dependant and wait. Almost 17 months in waiting now.
If you are a Canadian citizen, you also get to vote. For us it is taxation without representation.
