Just googled, too. And I'm still very suspicious for several reasons.
None of the sites I saw seem to know more about the group than the acronym FFFC, still they are all certain these people are anarchists. However, it is said they claim "to act on behalf of" Canada's aboriginal peoples. Right, this is exactly what anarchist DON'T do, anarchists very strongly advocate the self-organisation of people. NOT acting on their behalf, or for them. It is still probable this group is some mislead kids with a lot of wrong ideas of what anarchism is. But.....
But on the other hand there is this G20 meeting in Toronto coming up in a few days, and protests are already being organized. Now, such an act of terrorism may just be what the doctor prescribed if - errm: certain people would feel the urge to criminalize these protests altogether and be able to put persons in the clink pronto for as much as participating in peaceful protests. What a pity that protests usually belong to one's civil rights in most Western democratic states :sarcasm off:. However, all you need is one illegal act of violence, and all protest can be given the label terrorist. Which will certainly stop some, or even a lot of persons joining the peaceful protests planned, and those who still participate can conveniently be labeled 'terrorists', too.
Anarchism has been given a bad name due to a small group of people who used the so-called 'propaganda of deed' to commit terrorist bomb attacks. This was way back in the 1890ies and up to about 1905, and the tactics were soon denounced even at their time by the majority of anarchists, one reason being the innocent victims claimed by these assaults, so this strategy was intolerable for anarchists. Today, one of the largest tendencies in anarchism is non-violence, BTW.
And yes, "the fire this time" goes back to the title of a book written by James Baldwin in the late 1950ies/ early 1960ies - The Fire Next Time. The version "the fire *this* time" has been used by left persons, usually with Marxist leanings (which BTW were shared by Baldwin).
The spelling also wouldn't be "Kanada", but "KKKanada".
With the information available as of yet, this bombing smells very suspicious to me. Cointelpro is what comes to mind.
