Expanding 1935-1967 Canadian Silver Dollar Collection

sel 69 l , that makes sense but its hard for me to drop 400 bucks on a rare good grade coin

when rough estimate I could get the rest of the years I need ( discluding 1945,1947,1948 ) for 700 bucks when there all ms60 +

I buy fillers on purpose and then evwentually try to purchase better ones. My reason is that I never intend to sell my coins, I would like to pass them to my children I have three to date and we are talking about another at the moment. I try to interest my children in my collections as my fateher and grandfater did. That said I would like to eventually split my collection's into several starter collections for my children, so the better coins would potentially be split up with the fillers serving as space holders once again.

do you guys think MS-62 is a good grade to collect at?

For Queen Elizabeth, you can get some really sharp looking MS63's for slightly above bullion if you shop around.
