I ferried XLS eastbound. CYYR to BIKF and then to Europe without MNPS Approval. They allowed us to climb to FL 430 thru MNPS airspace on both legs. Next time I ferried CJ1 westbound. EGPC to BIRK, then BGBW and CYYR. All the time at FL280. No problems with VHF coverage. At EGPC you can rent immersion suits and life raft and then return them at CYYR.
PM me if you need more details.
