You can check standard processing times for applications here: http://www.cic.gc.ca/english/information/times/index.asp
For visitor visa, it takes about a month usually.
For parental residency applications, they're working on applications submitted in January 2014 at this time. Assuming this is an application for them to move to canada, you can expect a wait of 4-ish years until they even get to your application. Then about 8 to 12 months to process the application.
The information you see online is as up to date as the information will be by speaking to a person at CIC.
If you still need to contact CIC, you can do so at 1-888-242-2100 in Canada only. They can't speed up applications or make any decisions.
