Just trying to help my girlfriend,if I'm in the wrong subreddit for something like this then just send me to the right place. Right now I'm like a dog without a horse.
I would try asking on /r/Quebec. Can you read French? There are some sources written by members of the FLQ in French, but I am not aware of anything by protestors.. but I'm not familiar with the literature on the subject so it might exist. I imagine some of the protestors went on to write about it after the fact.
