You saying Canada doesn't have Digikey, Mouser, Newark, Arrow, ...
Design, buy, build. Buy extra when it is practical, for the price breaks. Stock the leftovers. If you buy stuff because you like to "have the ability to build stuff whenever I want," you are deluded in the time it takes for the design phase.
I have a few solderless breadboards, just for testing stuff I'm not 100% sure off. I wouldn't build anything big or complicated solely on breadboard. If I need 14 breadboards for some project, I'll know when I am undertaking the project. And I think I have a week to kill sorting out other details while the breadboards are being shipped.
You're in a phase. Some people go all out in this phase and amass giant labs filled with raaco drawers of parts. They or their families eventually rid this junk in firesales.
The entire awesomeness of electronics over mechanical machines is the ability to recreate or mass produce insanely complex things rather easily. But if you are hodge-podging things together in a breadboard and protoboard, you will have to debug your own mistakes in order to reproduce them. You shall learn to use CAD to make schematics and PCBs, eventually, and have ERC/DRC checks. You will also change over to SMD components. Or you are simply doing it wrong.
Almost every analog circuit that you might ever "discover" by sitting in a room full of components and randomly plugging them together has already discovered 50 years ago. And it now available in an integrated circuit in 2000 variations.
Don't fall down this rabbit hole. It's a phase.
