On average, I estimate once per month I'll be crossing back & forth. My US destinations will typically be Detriot area and/or north central Indiana-Ohio border area.
Within Canada, I may get one or two shots at hand-carry air delivery between YYZ and YWG from now to August. Might even be able to shoot it over to YVR or YQQ after staging at YWG.
For any cross-border or air exercises, I would want to inspect the contents of the box, so I can truthfully answer any questions from the authorities.
Might be a good plan to cut back on the heavy items if we have to ship inside Canada.
