You can use Geocodio to find the Census dissemination areas, tracts, economic regions, and more in bulk given an address or latitude/longitude coordinate pair.
You can download an example of the results when you add data from Statistics Canada to a list of addresses or coordinates with Geocodio here. You can see a tutorial for adding Statistics Canada geographies here.
Note that Canadian addresses must be accompanied by "Canada" given exactly, whether as a column in the spreadsheet (multi-column format) or in the address (single-column format). See examples here.
If you'd prefer to use an API to single or batch lookup Canadian Census geographies, you can see Geocodio's technical documentation here.
Requests are billed as geocode + StatCan info (i.e., two lookups). For example, if you have 100 addresses that you want StatCan boundaries for, that would count as 200 lookups.
You can calculate how much this will cost you and how long it will take here. Note that prices are in USD.
