Ideally you would withdraw a crypto from Kraken to another exchange to trade it for the crypto you want. There are very few cryptos that are paired to CAD, usually just BTC and ETH and Kraken has XRP. Note you will be charged a small withdrawal fee and depending on what you're withdrawing the transfer can take some time (as is the case for BTC and ETH these days).

LTC I think you can get on Kraken via BTC? So I would just do that. You can play the long game and buy BTC when it's dipping (say, today or tomorrow) and then buy LTC with that BTC when BTC is up and LTC is down. Right now I think BTC may bounce back a bit on Monday. LTC has been consolidating in a downtrend.

Don't wait for new pairs, there is no way to predict when that will happen.
