I'm not sure they're asking the right questions of you. If they _need_ an SSN and you can't get one, then you use an ITIN, but I wonder from your post whether they know what they're on about. If you're in Canada and they're issuing you a T4, you don't need an ITIN, you use your SIN as normal, you fill in your T1 as normal using the T4 they issue you. Sounds to me like they may not be up to speed on Canadian tax laws.
If you're employed in Canada and you do the work there, you don't need to file a US return so why do they need an SSN/ITIN at all? It's entirely legal for you to go to meetings in the US without doing a US return.
If they issue you a W-2 and/or you need to fill in a 1040NR then you probably need an ITIN.
Healthcare benefits in the US are of no use to you unless you want to travel to the US for treatment. Unless they have a dental plan or something like that you can claim on in Canada, but that would be unusual. They are aware that healthcare is nationalised in Canada, right?
I don't know who you're dealing with but it sounds to me like they're new to Canada!
