Inferential Statistics on long-form census data from stats can

I am using the following tool https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=9810065601 to query Statistics Canada and get data from the long-form census. However, since it’s a census of 25% of the population, there is a need for inferential statistics. That being said in order to do inferential statistics on the numbers I come up with, I am going to need variance estimates. Does anyone know where I can get those variance estimates?
