Are there Jihadis in Canada?

Of course there are. Some are in jail.  Others are in hiding.  Others are busy spreading the word:

CanadianJihad.ca documents public statements made by Canadian imams, Muslim scholars, and Islamic activists who advocate extremist ideas that undermine Canadian principles of freedom, democracy, pluralism, the rule of law, respect for minorities and the separation of mosque and state. In some cases, it shows Muslim leaders actually promoting violence, including murdering infidels.
