Thunder Bay only climbs 52m from the lake (183m) to the highest points near downtown (235m), the highest built-up parts are 283m. When you approach Thunder Bay from the east, the last 15 or so km of highway before the city is higher up above the lake than the city. In some places, there is a 150m incline over only 2 km, which is pretty steep for non-mountains in this region.
Mount McKay, south of the city, rises 250m over a distance of only 350m.

Downtown Port Arthur. The gap between the two under-construction condos on the left and the government building in the centre will be filled in with a Delta Hotel later this year.
