It varies.
It could be two or three years within the federal level—sometimes less than that—but then it has to go to the provincial level, and it could take another two or three years.
What you need to understand is that by the time a drug reaches the market the 20-year patent has already used at least 10 years of its lifetime. For a product developer to produce a drug into the market, they basically have another 10 years of exclusivity. If it takes another six or seven years for the approval in Canada, basically what you're telling the developer is that they have three years to make up their investment, which is really very small.
