This is do-able. You say you have the outline to Canada and all it's provinces in Photoshop, well, just make a new layer and create a solid black box that is just bigger than Canada and place this below the outline layer as a base.
Next, make another layer and onto this paint in one of the provinces in white. Delete the outline layer, merge the black background and the province layer and export.
In Bryce create a terrain, go into the terrain editor, click new and load first photoshop image, use the clipper bracket so you are left with the province and return to scene, then, click the "A" attributes box and resize this the same as the exported photoshop image, if it's too large just reduce it down, keeping the same ratio.
Go back to photoshop and click the back button until the grid returns and repeat for each province.
In Bryce, duplicate (ctrl + d) the first terrain, go into the editor click new and load the next image.
Each province should then fall exactly into place and be the correct size!
