Matt Paint availability?

[Bruce Parker (RIP)]

It seems you can no longer get matt paint in Ontario because of new regulations prohibiting oil based paint (except for licensed users which means private people are effectively out of luck), and water based paint doesn't come in matt.

Semi gloss water based paints can be colour matched and are fine for some applications but to do a WW2 CMP in the correct chalky matt seems no longer possible, at least here in Ontario.

Does anybody know the details of this ban? Is it really what I am thinking?

If there is a ban, is it only in Ontario or Canada wide?

Is is legal to import oil based paint from the USA or will it be stopped at the border as a 'controlled substance' needing some special permit?

Is there a home made additive that might matt a semi-gloss water based paint?
