The linked Wikipedia article notes English-speaking Canada officially uses the English version of SI notation:
1 234 567.89
and unofficially uses:
1,234,567.89
while French-speaking Canada uses the French version:
1 234 567,89
The one that really confuses me is the interpunct.
1,234,567·89
Malaysia, Philippines (uncommon today), Singapore, United Kingdom (older, typically handwritten; in education)
