Change is inevitable.
I have fond memories of going to the Planetarium as a child and gazing up at the (virtual) stars in wonder.
When my children were toddlers, we spent many happy hours at The Children's Museum housed in the Planetarium building.
Now plans are afoot to demolish the building and create a "mega-cultural complex," including a new Jewish Museum of Canada, according to a Toronto Star article.
People will scream and cry about the change, but the site has been underused for a long time and... change in inevitable.
