Hi rooneydog,
This plate is known to have an unerased guide line on the right side of the plate that passes through most of the stamps in the right column (so stamps 10, 20 ... 80, 90). This line is angled slightly so that it passes through each stamp in the column at a different location of the design. I believe that the line does not actually reach position 100 and that the line traces on the right side of that stamp are related to the well-known re-entry and are not part of the guide line.
The position of the guide line on your stamp indicates that it must come from position 90. The break in the lower left frame line is also normal for that position. The guide line was used for the original layout of the plate and it not related to a re-entry.
Although your stamp represents a unique and constant variety with its unerased guide line at right and broken left frame line, it is not a re-entry and is not currently assigned a Scott number or catalogued in the Unitrade Specialized Catalogue of Canadian Stamps. Nice stamp though!
