How often do you use WhatsApp?

I have friends all over Canada. In Brazil, we're used to using WhatsApp for pretty much everything, like staying in touch with friends and family, work-related communication, scheduling appointments, online shopping, dating, local communities, etc.

However, I'm facing some difficulties since it appears that WhatsApp isn't as widely used in Canada, at least not in Toronto
Am I mistaken or wpp is not a thing here? How frequently is WhatsApp used in Canada?
