Investors haven't been crying over the performance of TearLab, shares of the company are up more than 200% in just the first six months of 2012. It\u2019s been ninety years since Canada\u2019s greatest achievement in biotech took place; the discovery of insulin by Frederick Banting and his assistant Charles Best, in 1922. While nothing since has matched that miraculous feat, it\u2019s not like Canada has been sitting still in the meantime. Canadian researchers have contributed to The Human Genome project, cracked the genetic code of the mosquito that carries the deadliest strain of malaria, and deciphered human chromosome 7, which holds the gene for cystic fibrosis. Today the Toronto Stock Exchange and The TSX Venture Exchange are home to 119 Life Sciences companies that have a total market capitalization of $21.4 billion.
