While the other items may turn up, you have a Not As Described dispute there.
Open the cases, one for each purchase, in the Resolution Centre at the bottom of this (and many other) pages.
The first suggestion (not a requirement) is to Contact the Seller.
Ignore it.
If you need detail for the Dispute, it would be simply, "the item was not in the package".
And when asked if I could have the CP tracking numbers for all packages the seller just told me he would re ship them all as they probably got lost .
Do NOT accept an offer of a replacement. It won't arrive either.
The seller will be required to send you return shipping, but many overseas sellers don't do this because international tracked shipping is expensive with Canada Post.
If he doesn't, you win the Dispute and you will be refunded.
If he does supply shipping, you must return what you received, and when he gets it back, you will be refunded.
