Yes, absolutely. Carbon pricing does spur innovation and help to support our clean-tech sector. Another example is in Ontario. In 2017 there were 5,000 companies in Ontario's clean-tech sector, employing 130,000 people and generating about $20 billion in revenue each year. These companies were benefiting from the cap-and-trade system and the price signal that it was sending, as well as some of the ways in which the revenues were being recycled to support further emissions reductions, emerging technologies and whatnot.
A carbon price and other complementary policies are important to support these industries. In many cases, we've actually seen similar leakage issues for clean-tech companies where they're born in Canada, whether it's ecobee in Ontario or a Canadian solar company with a head office in Guelph or Corvus Energy. Many of these companies end up taking a large portion of their operations and the jobs to other markets where they can find more buyers. These are job and economic concerns that are worth considering.
