Not sure. Maybe some Canadian experts have the answer. Analytically speaking yes & no. Just run a screen with TSXV and sort by market cap. There are 2 companies with 2B+ market caps. The rest is drops off quickly. By the 60th stock by market cap we are at less than $100M
Raising VC in Canada is rather difficult so a lot of companies go the route of listing on the TSXV. The TSX Venture Exchange is a public venture capital marketplace for emerging companies which include resource exploration companies, high technology and life sciences ventures. Every once in a while a resource company will strike gold, diamonds or whatever and you can make a pile of money. But it is like buying a lottery ticket. Most of the time the company fizzles after a year or two then gets taken over by another company wanting to be listed. Often the nature of the business completely changes.
Anyways they are a step up from OTCs as stocks listed on the TSXV are allowed within RSPs (Canadian tax sheltered plans).
