Cmhc for retail+rental building

[Colin Davis]

First-timer buyer. Owner-occupied.

From what I understand in order to buy a 3-4 unit building with less than 20% down I must have CMHC mortgage insurance. I remember reading that one of the units could be commercial space as long as it is less than 50% of the building, but I cannot find any info about this on the cmhc site.

Am I remembering this correctly? Can I get a conventional mortgage with 10% down on a 3-unit building where one of the units is a commercial space accounting for half of the square footage?

Thanks
