I don't know how many in total, but too many are getting caught loitering in Canada when they were supposed to drive straight through.
The way it's looking right now, I'm not sure it makes any difference if Americans take their sweet time driving through. In August, Canada was averaging <500 cases per day. On Nov 1st, we had 3,244 cases. Yesterday we hit
5,500.
I don't know if the Atlantic Province Bubble will be able to withstand that kind of pressure. Yesterday, Nova Scotia reported no new cases after several days of worry over a mini-outbreak, when we accumulated about 20 new cases within a week. It'll be a few more days before we will know if we dodged another bullet. The advantage of having so few cases is that it enables rapid contact tracing and isolating where necessary.
