I'm not sure we have an easy answer for that or a simple method to reach them. I can use my own example. Perhaps you're in a similar circumstance. My sister and I give our elderly mother a lot of advice about what to answer and what not to answer, and we ask her to check with us on things. If you will, you educate those to educate others.
You're right. For those who are perhaps new Canadians with less familiarity with French and English and for some elderly populations, we need to go through intermediaries. We reach out as broadly as we can, but I won't pretend that we can reach everyone.
