don't see them selling often, and don't see people in a rush to drop or get rid of them either. I think their day will come. Aside from words, letters like C, A, S are probably best, or the letters of provincial acronyms, like NBT, BCA, ONT. I say follow the trends in .com, because .ca will follow behind in time, like with LLL, NNN, L-L, N-N, etc.
