Has anyone been summoned for jury duty?

Has anyone been summoned for jury duty? I'm terrified of being called to jury duty and having to talk in front of a bunch of people when answering questions, and as usual wasting everyone's time by stammering, and not giving my actual thoughts due to the speech impediment. According to my questionnaire, the chance to get chosen will start in 2020. On the questionnaire there was a section that stated disabilities but my dad told me not to check it, or rather he doesn't understand that I have a pretty big stammer since we hardly talk to each other. I sent the form but now regret that I didn't check that off, but at the same time I haven't yet gone to a doctor to discuss it. I'm planning to setup a doctors appointment to discuss my speech impediment. ​ But i'm wondering if being someone who has consistent stammering, can we get out of jury duty for it if we are summoned? Is there anyone that has been summoned to jury duty, and how was it like as someone who stutters or stammers? do you have to talk a lot? ​ I'm in Canada, so I'm not sure how it differs from other countries. Personally it makes me nervous to think about it. Would appreciate some insight.
