I've been doing the 'buy Canadian' thing for a few years now. I actually enjoy the game of trying to find cool folks making cool stuff and I know that there are others like me just like there are people who lack the time or inclination to do the research.
I also think it can be tricky for people looking at starting a business to be able to identify a need.
So what's a product you don't know of a Canadian alternative to?
Personally, it's cast iron cookware. Meyer makes great stainless stuff, but there isn't a single foundry making cast iron cookware in Canada. I've actually started emailing a few to see if I can find a Canadian foundry that would be willing to batch produce cast iron skillets. Finding a local brand already doing it would be a LOT easier!
If you are talking drip coffee may I suggest you move to a french press or some other way of brewing coffee? I moved to a French press years ago and never looked back, sure drip coffee is easier but it is not for me.
