Do you cover all of Canada?
We cover southern Canada, including Vancouver, Calgary, Winnipeg, Toronto, Montreal, and Halifax. The northern territories (Yukon, Northwest Territories, Nunavut) fall outside our detection range.
Are Toronto and Montreal included?
Yes, both are well within the covered latitude band.
Why is there a latitude limit?
It's a fixed technical limit of our detection range, not a deliberate coverage choice.
