It won't affect your Top Rated Seller status because we get the Global one not the tougher US one.
The Global TRS gives you the same discounts and sales, more or less, but the badge does not show if your customer sees your listing on dotCOM.
OTOH-- we don't need no stinkin' badges. Frankly few buyers ever notice them, or feedback, because they keep buying from incompetents with 95% FB. (/rant)
Tracking would depend on the item value but also on the category.
In some high fraud/high value categories (electronics, fine jewelry, sneakers, horse tack, dolls) tracking is very important.
I sell used books, sewing patterns and stamps. My customer demographic is painfully honest. I track very little.
But.
With Canada Post, if your item is bulky enough for parcel rates, it will probably be tracked anyway.
I think the only exception is Small Packet USA - which is half the price of Tracked Packet.
