How can I find reliable smart home solutions provider??

I and my team are looking to product sourcing to enable us to take advantage of the growing smart home market in Canada. So I’m finding a reliable smart home solutions provider to work with. I’ve spent a lot of time researching smart homes and home automation on Google and have found a few good companies like Control 4, LifeSmart, etc. but still want to find more manufacturers to compare. Any other good places to get info?
