for the new set, some items are still available from the canada post. you can either call them or check online. you may get more items if you call them, but long wait. or check with the main post office(i don't know do they still have it, but usually they have the most)
the post office at china town may have it, but not the original price.
don't go to the crystal mall, they have "big lion mouth".
currently there is a stamp show which is going to end tomorrow, can't remember is it in the hotel at hastings & renfrew or the hotel just across of richmond center, you can call the hotel to check it out. they may not have it with them, but if you tell them what you want, they can lsearch for you. i used to deal with the one called "xxx & son", its price is much more reasonable.
for the old set, you can still get it from auction, if you are lucky, not that bad
or if you pay me enough, i can sell it to you
I used to collect the stamps too.. ages, ages ago though. Darn I feel old @@
I still have the old canadian set in Ox 1997, Tiger 1998, Rabbit 1999, Dragon 2000, Snake 2001, Horse 2002, Sheep 2003, and Monkey 2004... and in every possible sheet/cut. Stopped collecting after the year of the monkey though~
