Canada?
Take a trip to California. 
Cali has great stuff if you know where to look. Unfortunately you'll still pay at least twice what we pay for up here. Up here, growers will give you garbage bags full of trim with very generous amounts of bud still left on the stalks.
My grower friend is an amazing chef and usually makes a huge batch of cannabudder after every harvest. He used pounds of trim (almost no leaf, pretty much pure bud) and simmered it for three days on a low heat. The cookies were so potent I puked after eating half and tripping for over 12 hours. The next weekend I tried a quarter of a cookie, same thing. I tried an 1/8th of a cookie the next weekend and didn't puke, but I "greened out" a few times but managed to redeem myself. I tried a 1/16th of a cookie, the size of a fucking Skittle and tripped BALLS almost as much as when I ate half a cookie... I just didn't puke or green out.
I got some budder and dehydrated some treats he made and used them for the next year whenever I got a headache. It was so potent. Much more potent than the most purified bubble and jelly hashes that I had ever smoked. I've seen techniques online for using volatile chemicals to extract the most clean, purified forms of THC you can basically rig up without a lab.. and I've had the pleasure of smoking some shit that's supposed to be on par with the techs I read on the internet. Just a wisp of smoke would have you on your ass and damn near puking. I had thought that I dropped LSD I became so out of it. Then I asked my mom where my mushroom burgers were in a fucked up haze lol...
I've had my grubby mits on some potent stuff, but some decently tended to, home grown is all I ever ask for. Something that's not laced with unnecessary/inappropriate nutrients, something that's been given the right light cycles, something that's been flushed properly of nitrates, dried appropriately and hasn't been rushed in the curing process. Honestly, you can use some half decent nutrients from the hydroponics store and as long as you have half a brain, you can grow the most amazing marijuana from bag seed (if you ever happen to come across it). People are just so God damn greedy, like the commercial growers. I only know few guys who grow at home and they become more and more reluctant to share over the years because people just abuse the shit out of it. It should be cherished and respected, imho.
Man, just went off on a weed tangent. If I didn't have a cold I'd track down some good bud. Maybe I'll make some weed goodies and watch a movie while I fight this cold...
