Are you using Quicken windows Canadian?
The Canadian version allows for importing from different currencies but the US version does not
The way the MS Money converter works is by calling MS Money through an API to send it the data. Sort of like programs can call Excel/Outlook to do things.
When I read this again, I wasn't sure if you were able to do the MS Money conversion or not.
If you were attempting to do that and couldn't here is some information on that.
You will need the Sunset version of MS Money installed. You can find that here:
Depending on how you use Quicken there are definite advantages/disadvantages between using the US or the Canadian version. The Canadian version has better multiple currency support, but unlike Quicken Mac, Quicken Windows US pretty much only supports US financial institutions, and the the Canadian version only supports Canadian financial institutions. What’s more a lot of the online features are US only, like the Lifetime Planner, Direct Connect (very few Canadian financial institutions even support Express Web Connect), Zillow, Credit Score, …
Also there are some quirks on the Canadian version like you can’t change the Home currency like you can on the US version (If you switch make sure you set this to what you want in your data file before switching.
I think the main driver would be where you have the most financial institutions if you have them in both countries.
Quicken Windows US will not import any data with a non-USD currency. Those transactions will have to be entered manually. The way it sits right now there isn't any good answer for you. If you go with the US version, the CAD accounts are manual entry only. If you go with the Canadian version, then it won't know about the US financial institutions, and they will be manual entry only.
The in between possibility is importing using the QIF format because it knows nothing about currency and as such there are just numbers in the QIF file, and it is the account that determines the currency. But QIF files have some really big restrictions in Quicken Windows Subscription. Here is more information on that:

It is one reason why people might choose to use my program (ImportQIF) to help with all the problems, but note it can't help with the fact that Quicken Windows Subscription will not match existing transactions during a QIF import. ImportQIF is free.
No, I haven't used it, but given the current state of Quicken Windows that might be your best bet. Note that Quicken Mac actually can download from both US and Canadian, so the limitation is purely in the Quicken Windows code.
