Done this a few times though I do have I/R.
'Tis possible VFR but I cannot recommend.
Suggested route Wick - Hofn - Reykjavik - Kulusuk - Sondrestrom - Iqaluit - Kuujjuaq then southwards wherever. Longest leg is Sondrestrom to Iqaluit at 490 nm.
Insurance would stop the project if you have not done it before. Common-sense suggests do it dual first and, no, I am not offering !
