The Canadian organ that handles immigration is called IRCC (Immigration, Refugees and Citizenship Canada).
It has currently around 8,600 employees, but chances are that none of them will pick up the phone for you.
So, being very straight forward, for most cases, you can't just pick up the phone and call IRCC.
If you have a specific question about your immigration application or the process in general, here are the actions you can take, in order of priority:
The IRCC web form is meant for questions and updates specific to your application. If your question is about the process in general, there is a big chance that your web form won't be answered.
The Web Form is a very useful resource, but it should be used as a last resource, as most of the important information can be found online on the IRCC website (links above).
The web form can be use for questions about your application and also updates to it.
There is no official response time for the IRCC web form.
Historically, responses might vary from only a few days to a few months. And sometimes you might even not get a response at all.
Some situations are recognized as urgent by IRCC and will be treated as such by them. For an example, currently IRCC will prioritize enquiries from people that were affected by the situation in Ukraine.
Normal requests like the ones below will not be considered as priority:
For urgent matters, like the current Ukraine situation, yes, you can call +1-613-321-4243.
But for all other non-urgent matters, you probably won't be able to call IRCC.
If you can't find the information you need online or on your application page, the best way to contact IRCC is through the IRCC Web Form.
Make sure that send all the information requested on the web form page, like:
Be concise and objective on the text you write, and consider that the response time might be long. Don't send more than one Web form for the same topic.
Give it some time. Response times might be long.
While you wait, try to find the information you need on your application page or on the IRCC website. There is a big chance that what you need is already there.
No. Sending a web form will not harm your application(s) in any way.
If you provide new information on the web form, that information might impact the application. But the fact that you sent a web form itself has no impact on it.
