Calls from Stats Canada
They use a large range of numbers in their outbound calls.  Likely each and every desk in the call centre has it's own direct number.

All the numbers they have tried to get me with from my call logs:
"STATS CANADA" <7804953379>
"STATS CANADA" <7804953457>
"STATS CANADA" <7804953847>
"STATS CANADA" <7804954610>
"STATS CANADA" <7804954613>
"STATS CANADA" <7804954614>
"STATS CANADA" <7804954617>
"STATS CANADA" <7804954760>

I'm sick woke me up 7 am I'm going to loose my [***] on them next call

they called I answered. no one there. most likely from stats Canada. and theres no sense blocking their number because they have over 100 numbers they call from. but most of them are from Edmonton alberta
