Actually I disagree with the advise. I would not cancel your mothers trip at all. Rather I would recommend for her to come here on a super visa as scheduled along with all her documents. then she soon as she lands i would immediately send a letter as well as call the Canadian hot line and inform them of the address change. Who cares if it takes a month or so longer when you get to have your mother with you much sooner (there is no warrantee how long she will wait after the medicals).
Once the address change is done, they will inform you to do the medicals in Canada and send it to either Ottawa or Mississauga. After that the passport request to an office in Canada and then you can do the border crossing with a road trip to the US. And all while your mother being at your side cooking you some nice home made food!.
I recommended based on recent Bogota LVO activity. Few things to note here:
1) There are only 2 cases out of total 320 LVO transfers of 2014 - 16 applicants. Statistically, this LVO doesn't seem that busy.
2) Both applicants of these 2 cases received Medical and PPR in same email (different from other LVO). If he had only medical request, I would have suggested otherwise.
3) The other applicant from 2015 batch received the email on 25-Jul, medical report received by Bogota on 8-Aug and then PR Visa stamped on 22-Aug. So, it was 3.5 weeks in total subject to how quick you do your medical.
4) In this case, I assume that his mom did the medical for Super Visa very recently. So, he can re-use this medical for immigration. The whole processing can take 2 - 4 weeks.
5) Lastly, to me, the most convenient way to land is by air. No need to make U-Turn on highway, flag-pole, cross border (not everyone lives near the border and not everyone has US visa) or make appointment with CIC (which takes months).
6) Additionally, the ticket cancellation cost can be recovered by suspending the SV medical insurance
Again, no one can absolutely guarantee that it will be processed within a month by Bogota. Same way, you never know when Ottawa slows down even for visa stamping.
