Cook Islands 2017 Commemorative Dollar

What is this? I can't find any information on these outside of the sale sites. Mine came in a PMG certified sleeve, graded at 70 Gem Unc

2017 Dollar - Skyline Series - 5g 0.999 Silver

Could it be under coins section? Can't read the bottom left bit. 

Also what has Cook Islands got to do with Toronto?

Thanks

 A different picture below. It is the Certificate of Authenticity 

It looks like they had a “Cities of the World” series, I found another one on eBay with Sydney on it.
