Canadian Satellite Radio Holdings Inc. (CSR), which offers satellite radio services under the XM Canada brand, has attracted more than 50,000 subscribers in its first three months of operations, the company announced March 6.

At the end of the company’s 2006 first quarter, which closed Feb. 28, XM Canada had 44,000 paying customers with the remainder on trial subscriptions. The company credited the subscriber growth to retail radio sales and said that its two auto deals, with GM Canada and Subaru Canada, have yet to contribute paying customers.

CSR, which launched service Nov. 22, expects to reach its subscriber guidance of 75,000 by the end of August, the company said.
