The changes take effect the end of October, which will make Ontario and Quebec the only regions where the familiar running-dog logo will continue to grace Canadian highways.

"This decision is regretful and we sympathize with the fact that many small towns are going to lose service," Greyhound Canada senior vice-president Stuart Kendrick said in an interview with The Canadian Press.

"But simply put, the issue that we have seen is the routes in rural parts of Canada — specifically Western Canada — are just not sustainable anymore."

Kendrick said 415 people will be out of work, and estimates the decision will impact roughly two million consumers.

The company blames a 41 per cent decline in ridership since 2010, persistent competition from subsidized national and inter-regional passenger transportation services, the growth of new low-cost airlines, regulatory constraints and the growth of car ownership.

Declining ridership is the primary culprit, said Kendrick, who called that and increasing costs an "ongoing spiral" that's making it impossible for the company to continue operations.

He said the company has raised concerns with provincial and federal officials over the years, and wanted to ensure both levels of government were "fully aware" of the situation. Greyhound Canada has long advocated for a community funding model to allow any private carrier to bid on essential rural services, he said.

'Significant losses'

Kendrick said Greyhound Canada will continue to push Ottawa to look at improving transport in northern communities.

"There was a commitment to look at our issue, they're well aware of it. It shouldn't come as a surprise that we've had problems, but there was no funding commitment at that time," he said.

"The company has experienced significant losses despite continued efforts to return to viability. In the affected regions, the company has run an operating deficit since 2004. We have had substantial losses over several years as a direct result of declining ridership."

All Greyhound routes in Ontario and Quebec will continue to operate except for one: the Trans-Canada, which links a number of smaller communities between Winnipeg and Sudbury, Ont.

Kendrick said the decision will leave most of the affected communities with no other transportation options.

Greyhound Canada applied to provincial regulators last year to discontinue routes in northern B.C. from Prince George to Prince Rupert because of declining ridership, cancellations that went into effect June 1.

The issue of adequate transportation came up repeatedly during the ongoing inquiry into missing and murdered Indigenous women and girls, since one of the affected routes included the notorious stretch of Highway 16 in B.C. known as the Highway of Tears, where a number of women have gone missing.
