I've checked my papers and I can't find that, but I'm sure I could have gotten a receipt and some form of confirmation.
You can always call the office and ask. They were a bit curt with me over the phone, but they did answer the questions I had.
I'm not 100% sure about ID requirements, also probably best asked over the phone.
I'd advise you to get a Netherlands ID card anyway, just because it's also proof of your Netherlands citizenship. If you ever were to become Canadian, you cannot let your Dutch passport or ID card expire a the risk of losing Dutch nationality. Loss of Dutch citizenship happens automatically for dual citizens unless you've been issued a Passport or ID card in the previous 10 years. Normally the Netherlands doesn't allow dual citizenship which is why loss is automatic, but if you're married to a person of the other citizenship, then you can keep it as long as you don't let documents expire.
If you become a dual citizen, having the ID card gives you extra security in case you forget to renew your Dutch passport and it expires. If you still have a valid ID card then you wouldn't have lost Dutch citizenship. My plan is to renew my passport in year 0, and my ID card in year 5, so there's always an overlap of a few years as both are valid for 10 years now. Previously ID cards could only be issued if you had your main residence in the Netherlands, but now Embassies abroad can issue them as well.
Of course, your spouse, if they aren't already, can become Dutch after living together with you for 3 years, as long as you're not living in Canada when you apply. In that case, there's even less risk of losing Dutch citizenship. Your spouse would also not have to give up Canadian citizenship to become Dutch.
