Trust in science is of course decreasing. Fortunately, it's not decreasing as fast in Canada as in other places, but we're not shielded. This is where we need to make sure that we're transparent and that we actually bring the maximum number of people into the understanding of science and of policy as well.
I don't think that lecturing the public is actually useful. My advice has been that we need to create opportunities for people to engage with science, with data.
My office put out a report on the sky Canada project on the observation of unidentified flying, or aerial, phenomena. Some people were surprised that we're dealing with this, but it was foremost to make sure that we gain public trust and that people don't think the government is hiding something, etc.
In government, I have assured a science integrity policy that all government departments with scientists have implemented to make sure that the science is done in a responsible manner and that scientists can speak publicly about the work.
There isn't just one thing to do; there are a number of things. I take trust in science and in institutions very seriously, because when people start distrusting one thing, they generally distrust everything.
