Excerpt:
A newly released intelligence report says hard-line Islamist groups want to build a "parallel society" in Canada, which could undermine the country's social cohesion and foster violence.
The de-classified Intelligence Assessment obtained by the National Post says extremists have been encouraging Muslims in the West to reject Western society and to live in "self-imposed isolation."
The report focuses on groups such as the Muslim Brotherhood and Hizb-ut-Tahrir, which do not advocate terrorist violence but promote an ideology at odds with core Western values.
