As a former Ottawa resident, I can relate. Most gas strut systems work in the cold initially, but when they begin to lose pressure, cold weather is when they will fail first.
I hope that the door design positions the struts so that they have good leverage to support the door. I also hope that the design specifies a fairly commonly available strut, so that they can be easily replaced when they fail.
As for sliding doors, I think the problem would be that the necessary tracks for the door would have a huge impact on the aerodynamic drag of the car, which is the car’s secret sauce, so to speak.
For sticking weatherstripping, I have found that an annual spray-down with silicone lubricant works wonders to prevent freezing in place.
