As a fellow Canadian, I recommend looking at the 3 main ETF providers' websites: iShares, BMO, and Vanguard. I know that iShares and BMO offer some sector specific ETFs. Also, if you are just getting started or are looking for a new trading platform, I recommend WealthSimple Trade. It is an app based (phone/tablet only, no computer platform) trading platform that allows you to trade completely free of charge (unless you use US listed ETFs, in which case they charge only a currency exchange fee)
