If you're coloring with Copic markers, don't color all of the way to the outside line because the ink will move.
If the ink does bleed outside of the image line, you can use the Copic colorless blender marker to push the ink back onto the image. It is not an eraser, but it does push ink. This works pretty well to get ink out of places where you don't want it.
And just fyi (so that you don't get really frustrated), be aware that no matter how careful you are, there is almost always a little bleed out somewhere on your image just because of the fluid/blending nature/quality of alcohol inks. And that's where the colorless blender saves the day
Have fun...........
As far as getting the Neenah paper, from what I've read the shipping from USA to Canada can be high, so you might want to see if you can find a source in Canada. You might contact Neenah directly and see if they can recommend a Canadian supplier.
Here's an SCS post, but although I didn't see any solutions for finding a Canadian Neenah supplier, some USA suppliers used by Canadian SCSers are mentioned:
