David Splane was at the international convention in Montreal sometime in the early 2000s (I can't remember what year it was).
He also visited one of the local congs in Ottawa a couple of times over the past 10 years since his wife is related to one of the elders there.
Anthony Morris gave the Canadian zone talk a few years ago. I can't remember exactly what he said in it other than he appeared very smug and I left the assembly hall thinking there's no way I'm surviving armageddon since I'm not pioneering. Luckily, I was already on the way out at that point and his talk just hastened my waking up.
