OK, so of course we're a few years behind the curve, but a few bubble tea places have opened up in ottawa. After trying the bubble tea at wang's noodle in the market, temptation tea shop on bank, and bubblicity on somerset, bubblicity is hands down my favorite.
Their menu is extensive (like all bubble tea places) but they have recommendations for first-timers so you don't get overwhelmed. The mango slush and taro latte were both great! Plus the service was excellent and the place was packed, but not uncomfortably so. I also had brick toast, which I've never even seen before; it constists of a literal brick of white bread, toasted, spread with different-flavored cream (and butter, I suspect). I tried coconut to be safe, but they also have fruit flavors, as well as garlic and cheese. It was odd, but very delicious.
The bubble tea at the temptation tea shop was fine, but it was kind of dead in there, and the service was a little slow. They have real food on their menu, which I think might turn out to be a mistake, since bubble tea is really more like a coffee-shop phenomenon.
