We're holidaying in Canada later this year (25th wedding aniversary
treat).
I may end up with excess baggage with
that much glass!

Brian answered your first question.
A 6" full thickness mirror weighs ~1kg
If you plan to buy a Canadian optical set in Canada there are some
things you need to know first:
It takes a long time to make a good optical set. I would recommend
ordering at least 3 months in advance.
Sales tax varies from province to province. It will add at least 7% to
the price.
Unless your vacation plan takes you to the city where your optician
live don't plan to pick up your optics in person. Have them shipped
to your hotel.
