St. John's to Victoria is 7100 KMs, with a ferry ride at each end , so probably a realistic 9-10 days of steady driving from coast to coast. The furthest I've driven is from Ottawa to Slave Lake Alberta (north of Edmonton), and that took 4 days. That drive is about 3600 KMs. The North-South times are, as @John Fedup indicated, difficult to quantify. Just identifying a start point in the Arctic is difficult (Arctic Archipelago | The Canadian Encyclopedia). In any case, @ngatimozart's point is well taken - it would probably be a 5000KM transit from either Halifax or Esquimalt just to get to the start of a patrol area in the Arctic.Nova Scotia to the BC coast is 6-7 days by car, might be able to knock day off by crossing the border at Detroit and driving across the US and then crossing back on the BC-Washington State border. Adding in a cross NL/ ferry to Nova Scotia would add at least 1-2 days. The drive to the Arctic from the US border depends on which part of the border. Big difference between the 49th parallel and starting from Southern Ontario or Nova Scotia. Explains why I miss planes.
