The Waze App wants to route me via Hwy 402 and cross into the USA. While I realize it's a shorter route, often the hold up times at the border makes it a much longer route in terms of waiting.
Also, it's a bit of a hassle to have to have passports for travelling inside our own country. I think at some point, having a toggle for "Avoid Border Crossings" like "Avoid Toll Roads" should be put into place. This would ensure that folks who live close to the American border (like 90% of Canadians) will not have to cross the border to travel within Canada.
Google Maps does this route (to downtown Toronto) correctly by routing to the 403:

Just my two cents, it's a great app otherwise!
