I hate to be the nitpicker but i havent really seen much to indicate any "real" terrorist activity.
They claim some of them went to a terrorist camp near toronto .. i have never heard of any terror camps before in canada ( although they prob dont advertise

)
Some of the evidence seemed a little shaky . They had a bunch of fertilizer that of course would be explainable if any of them were farmers.. 1 or 2 guns ( whoopeee ) a supposed remote detonator ( looked hand built and shady at best , not exactly "quality" work )
Seems more likely its one bad guy who was an extremist who was trying to groom some future terrorists , one of them prob told the cops " this guy seems shady and up to no good " , wham bam thank you maam they are all arrested.. considering the fact canada usually throws the book at non-violent crimes and lenient on violent whacko's im sure they will be released soon or brought up on useless charges..
