[Talk-ca] "Canada Data Import Status" was edited recently

Thanks Frank,
i'll update the chart with the tile names, i saw it before but i just
couldnt find it the 2nd time looking. :)

im now saving the canvec zip files with the version number, so thats good.
The detail that i need from CanVec is the 'last date of survey' this
different for each tile. And regardless of v3 or v4, this is what
tells us how old the data is (so to compare with different data as
available). So to keep track of this info, 1 row per tile is needed.

I could make a separate (new tab) for each longitude interval, but
then the rows cant be sorted.

Anyone have ideas?
