Vaccine hesitancy: Why ‘doing your own research’ doesn’t work, but reason alone won’t change minds

Restoring community dialogue and resilience: The next COVID-19 emergency

Canada’s ‘us against them’ COVID-19 strategy is amplifying social division, creating major psychosocial impacts, and has resulted in a significant decrease in trust toward authorities.

Everyone should be concerned if the federal government bypasses the Canada Gazette

In a time-honoured tradition of Canadian democracy, government regulations become public when they appear in the Canada Gazette. That’s why Ottawa’s proposal to bypass that step is so troublesome.
