Never Seen this Postmark Before

[Phil]

Is this a normal cancellation for Canadian Stamps? I don't recall seeing it before

I found some stock pages and these, along with several others all had that same double-bar cancellation.

tony is correct, they are Canadian pre-cancels.

The numerical pre-cancel is a Style 10 precancel; 4035 pre-cancel is for Peterborough, Ontario.

The 3 pairs of lines are Style X pre-cancels.

The 2 pairs of lines are Style Y pre-cancels.

OK, that makes sense now. Thanks!

I honestly don't recall seeing this before. I probably noticed it because they were all together.
