No, not that kind of diversity! 
Any Canadian pilot will be well aware of the bandying about, about the upcoming requirements for transponders with diversity options with bottom and top mounted antennas so NavCanada can use their satellite based 1090 ADS-B. It could result in a huge cost, throwing away perfectly good equipment (already cert. for US ADS-B) and gaining essentially no added benefit for the pilot-owner, other than complying with regs.
Well, there have been some quiet changes to the initial regs, that have not been much publicized, and they portend great news. I'll just quote from a post on another forum ....

..... You may not actually need to replace your transponder to meet the mandate.
Despite all the messaging that says you need diversity to be received by the satellites, Nav Canada / Transport Canada quietly made some updates this summer to their websites and the CARs.
The Nav Canada website has a link to CARs 551.103 on this page under equipage requirements:
NAV CANADA ADS-B Performance Requirements
If you read through that section, you'll see a bunch of changes / notes that were added in July, including the below snip.
Based on that, my understanding is that you can request a performance report after one of your flights (or a few to be safe) and if it passes all the metrics, you are good to go. Just need to add SUR/CANMANDATE to your flight plan codes.
Performance reports can be requested here: NAV CANADA Public ADS-B Performance Report
My plane passed completely with the AXP-322 and only the bottom mounted antenna.
