Science and research matter.

They are fundamental building blocks of Canada.

We need a minister with research in their title.

Research leads to innovation and
economic growth.

Time for Canada to lead and welcome researchers to build Canada.

My family was burglarized while sleeping in an @Airbnb, > $21K USD in valuables stolen

Promised security and “AirCover”? We got nothing

They've ignored claim, deleted my review, burying the truth

Arbitration coming, @bchesky-fix this!
