I am also in Canada.
I ordered from ereader.store, which is located in Germany, and was very satisfied. However, the delivery service I used, UPS, is now significantly more expensive from this distributor than it was when I pre-ordered, perhaps due to the large size of the two packages. Since the Mira Pro is less expensive from ereader.store, it is still relatively similar in price to order internationally with DHL shipping. Unfortunately, this option is said to take 1-4 weeks to deliver depending on destination. I recommend this shop to those in Europe due to the free and fast shipping there.
If you are ordering from Boox themselves, the Chinese shop offers free but slow shipping to Canada. I have not inquired to the US shop, but it is disappointing that you have not heard a response.
My reservations about the Mira Pro are:
(1) If you are sensitive to light, it may be a challenge to find a suitable light source. I do best when my Mira Pro is lit with natural light.
(2) I find heavy scrolling on e-ink is painful in its own right. I do not casually browse the web on this monitor, as it is no exception. I am disappointed by this, but I think it is due to limitations in e-ink technology.
(3) My eyestrain has gotten worse anyway. This is an odd finding, as I find the e-ink more comfortable. Perhaps the monitor is not more comfortable and it is just my bias after purchasing an expensive item. However, what I find likely is that e-ink did not solve my preexisting Binocular Vision Dysfunction and the monitor was not able to change the trajectory of my symptoms, which was already worsening when I received the monitor. This is all to say that I prefer to the use monitor as I have less symptoms with it, but it was not the miracle I had hoped it would be.
I think (2) is the most important consideration for most people.
Something positive -- I can use modern Windows 10 and Windows 11 on this monitor. This is a development as I have been using an ancient version of Windows 10 (1507) for years. EDIT: Unsure about Windows version, I need to retest.
