Where to buy Residual Hypo Test (HT-2) in Ontario Canada

Does anyone know of an outlet in Southern Ontario where I can buy a version of a pre-made HT-2 Residual Hypo Test kit?

or

Perhaps you make your own, live in the Greater Toronto Area and would be prepared to sell me a bottle!? (PS I even have the small brown glass bottle to out it in)

Thanks in advance

Todd -- it looks like it just has silver nitrate and acetic acid in it. Silver nitrate is not that cheap but I do have some around. How much do you need?

I can likely give you a hand as well

I am in south mississauga on the oakville border, if that is an easier solution. Or we can do it by canada post.

I do not have the darkroom cookbook at hand, but I have a bit of almost all raw chems required as constituent ingredients for things photographic in the B&W world, and am rather confident that it should be creatable from onhand stocks.
