If Samsung releases it for sale in Canada, I expect Telus will carry it - they did the last model released in Canada the S5 Active. Samsung Canada's website has no mention of this phone, so thus far, it is not available for sale in Canada.
@Sylvaticus Thank you for your suggestion. While the S7 Active did not make it into our device selection, we encourage you to continue suggestions devices you would like to see through TELUS.
