Here's the letter:
the source. And here's some background on Mr. Lemire, including his wiki entry, from which I quote: "Lemire was the last president of the often violent Heritage Front organization from January 1, 2001 until the organization folded around 2005". If Mr. Chisu was living in T.O. back in the mid 1990s to early 2000s, he should have heard of this guy. I will send his office a quick email, and see if he remembers.
PS. A reader notes that Lemire
...the last known president of the Heritage Front, was working for Mr. [Ernst] Zündel part-time, and then full-time for many years until Mr. Zündel left for the United States.
...and that CPoC Minister Vic Toews has reitereated that Mr. Zundel is not welcome back in Canada.
