Any store that sells reloading supplies should have 209 primers.
I bought a flat of Win AA and shot them in skeet and trap, kept the hulls, and started out with those for 00 buck and slugs. I later picked up ~500 Federal high brass hulls when the police did shotgun qualification at the range I'm a member at and left all their hulls.
Wads I buy local but several retailers carry them. Henry at Budget as mentioned but also Bilozir Fine Guns who are the Canadian distributor for Ballistic Products stuff from the US. If you want fibre wads, Track of the Wolf in the US is where I get mine.
For buffer I use cream of wheat from the Bulk Barn. Really helped with my buckshot loads (shrunk groups by ~25%) and costs a fraction of what the plastic powder buffer does. Just don't get it wet.
I have a Lee 7/8oz mold but can't find a load that will shoot them worth a damn. No matter what I try (different screw in chokes, different loads, and a fully rifled barrel) they don't seem to work well.
The 1oz Lee slugs I cast I have several loads that will group 4-6" @ 50yds out of a smooth bore with IC choke. Still can't get them to work in a fully rifled barrel.
For 00 buck I use the Lee 18-pellet mold. Kind of annoying clipping the shot apart but for the price, I can't really complain. Stacks in 2's for 4 layers inside a shot cup, or if I use fibre wads and no shot cup, 3x3.
All my molds come from Titan Reloading in the US. Shipping is faster than many Canadian retailers and they were much cheaper than Canadian retailers when our dollar was up. Now that our dollar is down, it's pretty much on par for cost, but I still order from them since they always have everything I want in-stock; no ordering from 3 different retailers or waiting weeks from a single retailer to put together everything I want.
I use a Lee Load-All 2 for 12ga and a MEC 600jr for .410. If you'll be loading thousands of shells a year, I'd pickup a 600jr, but if you're loading a couple hundred a year at most, a Lee LA2 will get the job done. You need to hand load the payload with any press anyway so even if you got a progressive press, you'd have to remove the shell to load the buckshot or slugs in so there isn't much point. If you want to go the MEC route, I'd try to find a used one. A 600jr. can run $250-300 new but often go used for $100 or so.
