The Canadian Securities Exchange (CSE) said trading volume on its listed stocks in the first half this year at 5.5bn shares was 175% higher than the same period of 2016.
Listed issues raised over $320mln in the six months, up 161%, with 217 financings completed, it added.
And the value of CSE listed securities traded was $1.6 billion - 586% higher.
"The tremendous growth in trading volume and financings at the CSE during the first six months of 2017 is a reflection of our listed companies achieving their objectives," said Richard Carleton, chief executive.
"It is a credit to our entire issuer base. The primary reason companies go public is to gain access to capital more easily and under better terms than they would experience in other contexts.
"As more and more companies accomplish this with a CSE listing, both the exchange and its issuers grow stronger.”
Technology, resource exploration and life sciences were among sectors experiencing markedly stronger investor engagement in the half, said CSE
Companies conducting financings in the first half included Namaste Technologies, which raised C$11.3 million, while Canadian Bioceutical Corporation carried out two financings raising a total of C$38.2 million.
Issuers focused on the cannabis industry accounted for around half of the funds raised, with technology and resource exploration companies also attracting significant amounts of new capital.
