This beautifully simple coat of arms shows the civic colours of the city (blue and gold), a fraise (for the Fraser river, which joins the Nechako river in the city- these rivers are also represented by the wavy fess), and two snowflakes (representing the northen location of the community. The salmon, eagle and falcon represent the wildlife of the area, the latter two wearing princely crowns (to reflect the name of the city) and having their wings tintured gold and blue (to make them unique). The moose (arising from a mural crown, fitting for civic armourial bearings) is also representative of the local fauna, and is taken from the crest of the original assumed device, shown below. The motto, "Shaping a Northern Destiny" is reflective of the northern location and regional importance of the city (and beats the heck out of trite phrases like "Industry Bravery Intelligence" which cities seem to cling to).

For some reason, the city seems to be continuing the use of this terribly unheraldic "city seal" on its web pages, despite having beautiful and honourable arms of its own. It has, in quarters, a train, crosses mining tools, a sheaf of wheat, and a tree, with a moosehead pretending to be a crest. Not quite as bad as the first device used by Ottawa, at least.
